+publish-to-git
+==============
+
+[GitHub Action](https://github.com/features/actions) for publishing a directory
+and its contents to another git repository.
+
+This can be especially useful for publishing static website, such as with
+[GitHub Pages](https://pages.github.com/), from built files in other job
+steps, such as [Doxygen](http://www.doxygen.nl/) generated HTML files.
+
+**NOTE**: GitHub currently requires the use of a Personal Access Token for
+pushing to other repositories. Pushing to the current repository should work
+with the always-available GitHub Token (available via
+`{{ secrets.GITHUB_TOKEN }}`. If pushing to another repository, a Personal
+Access Token will need to be [created](https://help.github.com/en/articles/creating-a-personal-access-token-for-the-command-line) and assigned to the
+workflow [secrets](https://help.github.com/en/articles/virtual-environments-for-github-actions#creating-and-using-secrets-encrypted-variables).
+
+Inputs
+------
+
+- `repository`: Destination repository (default: current repository).
+- `branch`: Destination branch (required).
+- `host`: Destination git host (default: `github.com`).
+- `github_token`: GitHub Token (required; use `secrets.GITHUB_TOKEN`).
+- `github_pat`: Personal Access Token or other https credentials.
+- `source_folder`: Source folder in workspace to copy (default: workspace root).
+- `target_folder`: Target folder in destination branch to copy to (default: repository root).
+- `commit_author`: Override commit author (default: `{github.actor}@users.noreply.github.com`).
+- `commit_message`: Set commit message (default: `[workflow] Publish from [repository]:[branch]/[folder]`).
+- `dry_run`: Does not push if non-empty (default: empty).
+- `working_directory`: Location to checkout repository (default: random location in `${HOME}`)
+
+Outputs
+-------
+
+- `commit_hash`: SHA hash of the new commit.
+- `working_directory`: Working directory of git clone of repository.
+
+License
+-------
+
+MIT License. See [LICENSE](LICENSE) for details.
+
+Usage Example
+-------------
+
+```yaml
+jobs:
+  publish:
+    - uses: actions/checkout@master
+    - run: |
+        sh scripts/build-doxygen-html.sh --out static/html
+    - uses: seanmiddleditch/gha-publish-to-git@master
+      with:
+        branch: gh-pages
+        github_token: '${{ secrets.GITHUB_TOKEN  }}'
+        github_pat: '${{ secrets.GH_PAT }}'
+        source_folder: static/html
+      if: success() && github.event == 'push'

-# Contributing
+# Contributing to Grafana
 
-Grafana uses GitHub to manage contributions.
-Contributions take the form of pull requests that will be reviewed by the core team.
+Thank you for your interest in contributing to Grafana! We welcome all people who want to contribute in a healthy and constructive manner within our community. To help us create a safe and positive community experience for all, we require all participants to adhere to the [Code of Conduct](CODE_OF_CONDUCT.md).
 
-- If you are a new contributor see: [Steps to Contribute](#steps-to-contribute)
+This document is a guide to help you through the process of contributing to Grafana.
 
-- If you have a trivial fix or improvement, go ahead and create a pull request.
+## Become a contributor
 
-- If you plan to do something more involved, discuss your idea on the respective [issue](https://github.com/grafana/grafana/issues) or create a [new issue](https://github.com/grafana/grafana/issues/new) if it does not exist. This will avoid unnecessary work and surely give you and us a good deal of inspiration.
+You can contribute to Grafana in several ways. Here are some examples:
 
-- Sign our [CLA](http://docs.grafana.org/contribute/cla/).
+- Contribute to the Grafana codebase.
+- Report and triage bugs.
+- Develop community plugins and dashboards.
+- Write technical documentation and blog posts, for users and contributors.
+- Organize meetups and user groups in your local area.
+- Help others by answering questions about Grafana.
 
-- Make sure to follow the code style guides
-  - [Backend](https://github.com/grafana/grafana/tree/master/pkg)
-  - [Frontend](https://github.com/grafana/grafana/tree/master/style_guides)
+For more ways to contribute, check out the [Open Source Guides](https://opensource.guide/how-to-contribute/).
 
-## Steps to Contribute
+### Report bugs
 
-Should you wish to work on a GitHub issue, check first if it is not already assigned to someone. If it is free, you claim it by commenting on the issue that you want to work on it. This is to prevent duplicated efforts from contributors on the same issue.
+Report a bug by submitting a [bug report](https://github.com/grafana/grafana/issues/new?labels=type%3A+bug&template=1-bug_report.md). Make sure that you provide as much information as possible on how to reproduce the bug.
 
-Please check the [`beginner friendly`](https://github.com/grafana/grafana/issues?q=is%3Aopen+is%3Aissue+label%3A%22beginner+friendly%22) and [`help wanted`](https://github.com/grafana/grafana/issues?q=is%3Aopen+is%3Aissue+label%3A%22help+wanted%22) labels to find issues that are good for getting started. If you have questions about one of the issues, with or without the tag, please comment on them and one of the core team or the original poster will clarify it.
+Before submitting a new issue, try to make sure someone hasn't already reported the problem. Look through the [existing issues](https://github.com/grafana/grafana/issues) for similar issues.
 
-To setup a local development environment we recommend reading [Building Grafana from source](http://docs.grafana.org/project/building_from_source/)
+#### Security issues
 
-## Pull Request Checklist
+If you believe you've found a security vulnerability, please read our [security policy](https://github.com/grafana/grafana/security/policy) for more details.
 
-- Branch from the master branch and, if needed, rebase to the current master branch before submitting your pull request. If it doesn't merge cleanly with master you may be asked to rebase your changes.
+### Suggest enhancements
 
-- If your patch is not getting reviewed or you need a specific person to review it, you can @-reply a reviewer asking for a review in the pull request or a comment.
+If you have an idea of how to improve Grafana, submit an [enhancement request](https://github.com/grafana/grafana/issues/new?labels=type%3A+feature+request&template=2-feature_request.md).
 
-- Add tests relevant to the fixed bug or new feature.
+We want to make Grafana accessible to even more people. Submit an [accessibility issue](https://github.com/grafana/grafana/issues/new?labels=type%3A+accessibility&template=3-accessibility.md) to help us understand what we can improve.
 
-- Follow [PR and commit messages guidelines](#PR-and-commit-messages-guidelines)
+### Triage issues
 
-### Pull Requests titles and message
+If you don't have the knowledge or time to code, consider helping with _issue triage_. The community will thank you for saving them time by spending some of yours.
 
-Pull request titles should follow this format: `Area: Name of the change`.
-Titles are used to generate the changelog so they should be as descriptive as possible in one line.
+Read more about the ways you can [Triage issues](/contribute/triage-issues.md).
 
-Good Examples
+### Answering questions
 
-- `Explore: Adds Live option for supported datasources`
-- `GraphPanel: Don't sort series when legend table & sort column is not visible`
-- `Build: Support publishing MSI to grafana.com`
+If you have a question and you can't find the answer in the [documentation](https://grafana.com/docs/), the next step is to ask it on the [community site](https://community.grafana.com/).
 
-The message in the Pull requests should contain a reference so the issue if there is one. Ex `Closes #<issue number>`, `Fixes #<issue number>`, or `Ref #<issue number>` if the change is related to an issue but does not close it. Make sure to explain what problem the pull request is solving and why its implemented this way. As a new contributor its often better to overcommunicate to avoid back and forth communication, as it consumes time and energy.
+It's important to us to help these users, and we'd love your help. Sign up to our [community site](https://community.grafana.com/), and start helping other Grafana users by answering their questions.
 
-### GIT commit formating.
+### Your first contribution
 
-Grafana Squash Pull requests when merging them into master. This means the maintainer will be responsible for the title in the git commit message.
-The commit message of the commits in the Pull Request can still be part of the git commit body. So it's always encouraged to write informative commit messages.
+Unsure where to begin contributing to Grafana? Start by browsing issues labeled `beginner friendly` or `help wanted`.
 
-The Git commit title should be short, descriptive and include the Pull Request ID.
+- [Beginner-friendly](https://github.com/grafana/grafana/issues?q=is%3Aopen+is%3Aissue+label%3A%22beginner+friendly%22) issues are generally straightforward to complete.
+- [Help wanted](https://github.com/grafana/grafana/issues?q=is%3Aopen+is%3Aissue+label%3A%22help+wanted%22) issues are problems we would like the community to help us with regardless of complexity.
 
-Good Examples
+If you're looking to make a code change, see how to set up your environment for [local development](contribute/developer-guide.md).
 
-- `Explore: Live supprt in datasources (#12345)`
-- `GraphPanel: Fix legend sorting issues (#12345)`
-- `Build: Support publishing MSI to grafana.com (#12345)`
+When you're ready to contribute, it's time to [Create a pull request](/contribute/create-pull-request.md).
 
-Its also good practice to include a reference to the issue in the git commit body when possible.
+#### Contributor License Agreement (CLA)

-
-### Request closing of issues
-
-The Grafana project have a lot of open issues and the main goal is to only have issues open if their still relevant. If you find an issue that you think already have been resolved or no longer is relevant please report by adding a comment and explain why you think it should be closed including related issues (`#<issue number>`), if applicable, and optionally mention one of the maintainers.
-
-### Investigate issues
-
-See [investigation of issues](#investigation-of-issues).
-
-### Vote on enhancements/bugs
-
-Helping the Grafana project to know which issues are most important by users and the community is crucial for the success of the project. Read more about [prioritizing issues](#4-prioritization-of-issues) for details about how issues are being prioritized. The Grafana project use GitGub issues and reactions for collecting votes on enhancement and bugs.
-
-**Please don't add `+1` issue comments or similar since that will notify everyone that have subscribed to an issue and it doesn't add any useful update, rather it creates a bad .**
-
-If you want to show your interest or importance of an issue, please use [GitHub's reactions](https://help.github.com/en/articles/about-conversations-on-github#reacting-to-ideas-in-comments).

-
-### Suggest ideas for resolving bugs/enhancements
-
-Related to how [issues are being prioritized](#4-prioritization-of-issues) it's important to help anyone that's interested in contributing code for resolving a bug or enhancement. This can be anything from getting started and setup the development environment to reference code and files where changes probably needs to be made and/or suggest ideas on how enhancements may function/be implemented.

 ## 1. Find uncategorized issues
 
 To get started with issue triage and finding issues that haven't been triaged you have two alternatives.
 
 ### Browse unlabeled issues

 When an issue has all basic information provided, but the triage responsible haven't been able to reproduce the reported problem at a first glance, the issue is labeled [Needs investigation](https://github.com/grafana/grafana/labels/needs%20investigation). Depending of the perceived severity and/or number of [upvotes](https://help.github.com/en/articles/about-conversations-on-github#reacting-to-ideas-in-comments), the investigation will either be delegated to another maintainer for further investigation or either put on hold until someone else (maintainer or contributor) picks it up and eventually start investigating it.
 
-Investigating issues can be a very time consuming task, especially for the maintainers given the huge number of combinations of plugins, datasources, platforms, databases, browsers, tools, hardware, integrations, versions and cloud services etc that are being used with Grafana. There are a certain amount of combinations that are more common than others and these are in general easier for maintainers to investigate.
+Investigating issues can be a very time consuming task, especially for the maintainers given the huge number of combinations of plugins, data sources, platforms, databases, browsers, tools, hardware, integrations, versions and cloud services etc that are being used with Grafana. There are a certain amount of combinations that are more common than others and these are in general easier for maintainers to investigate.
 
 For some other combinations there may not be possible at all for a maintainer to setup a proper test environment for being able to investigate. In these cases we really appreciate any help we can get from the community. Otherwise the issue is highly likely to be closed.
 
 Even if you don't have the time or knowledge to investigate an issue we highly recommend that you [upvote](https://help.github.com/en/articles/about-conversations-on-github#reacting-to-ideas-in-comments) the issue if you happen to have the same problem. If you have further details that may help investigating the issue please provide as much information as possible.
 
+## External PRs
+
+Part of issue triage should also be triaging of external PRs. Main goal should be to make sure PRs from external contributors have an owner/reviewer and are not forgotten.
+
+1. Check new external PRs which do not have a reviewer.
+1. Check if there is a link to an existing issue.
+1. If not and you know which issue it is solving add the link yourself, otherwise ask the author to link the issue or create one.
+1. Assign a reviewer based on who was handling the linked issue or what code or feature does the PR touches (look at who was the last to make changes there if all else fails).

+Grafana allows you to query, visualize, alert on and understand your metrics no matter where they are stored. Create, explore, and share dashboards with your team and foster a data driven culture:
 
-## Installation
+- **Visualize:** Fast and flexible client side graphs with a multitude of options. Panel plugins for many different way to visualize metrics and logs.
+- **Dynamic Dashboards:** Create dynamic & reusable dashboards with template variables that appear as dropdowns at the top of the dashboard.
+- **Explore Metrics:** Explore your data through ad-hoc queries and dynamic drilldown. Split view and compare different time ranges, queries and data sources side by side.
+- **Explore Logs:** Experience the magic of switching from metrics to logs with preserved label filters. Quickly search through all your logs or streaming them live.
+- **Alerting:** Visually define alert rules for your most important metrics. Grafana will continuously evaluate and send notifications to systems like Slack, PagerDuty, VictorOps, OpsGenie.
+- **Mixed Data Sources:** Mix different data sources in the same graph! You can specify a data source on a per-query basis. This works for even custom datasources.

-**The project located in the go-path will be your working directory.**
+## Get involved
 
-```bash
-go get github.com/grafana/grafana
-cd $GOPATH/src/github.com/grafana/grafana
-```
-
-### Run and rebuild on source change
-
-#### Backend
-
-To run the backend and rebuild on source change:
-
-```bash
-make run
-```
-
-#### Frontend
-
-Rebuild on file change, and serve them by Grafana's webserver (http://localhost:3000):
-
-```bash
-yarn start
-```
-
-Build the assets, rebuild on file change with Hot Module Replacement (HMR), and serve them by webpack-dev-server (http://localhost:3333):
-
-```bash
-yarn start:hot
-# OR set a theme
-env GRAFANA_THEME=light yarn start:hot
-```
-
-_Note: HMR for Angular is not supported. If you edit files in the Angular part of the app, the whole page will reload._
-
-Run tests and rebuild on source change:
-
-```bash
-yarn jest
-```
-
-**Open grafana in your browser (default: e.g. `http://localhost:3000`) and login with admin user (default: `user/pass = admin/admin`).**
-
-### Building
-
-#### The backend
-
-```bash
-go run build.go setup
-go run build.go build
-```
-
-#### Frontend assets
-
-_For this you need Node.js (LTS version)._
-
-```bash
-yarn install --pure-lockfile
-```
-
-### Building a Docker image
-
-There are two different ways to build a Grafana docker image. If your machine is setup for Grafana development and you run linux/amd64 you can build just the image. Otherwise, there is the option to build Grafana completely within Docker.
-
-Run the image you have built using: `docker run --rm -p 3000:3000 grafana/grafana:dev`
-
-#### Building on linux/amd64 (fast)
-
-1. Build the frontend `go run build.go build-frontend`
-2. Build the docker image `make build-docker-dev`
-
-The resulting image will be tagged as `grafana/grafana:dev`
-
-#### Building anywhere (slower)
-
-Choose this option to build on platforms other than linux/amd64 and/or not have to setup the Grafana development environment.
-
-1. `make build-docker-full` or `docker build -t grafana/grafana:dev .`
-
-The resulting image will be tagged as `grafana/grafana:dev`
-
-Notice: If you are using Docker for MacOS, be sure to set the memory limit to be larger than 2 GiB (at docker -> Preferences -> Advanced), otherwise `grunt build` may fail.
-
-## Development
-
-### Dev config
-
-Create a custom.ini in the conf directory to override default configuration options.
-You only need to add the options you want to override. Config files are applied in the order of:
-
-1. grafana.ini
-1. custom.ini
-
-In your custom.ini uncomment (remove the leading `;`) sign. And set `app_mode = development`.
-
-### Running tests
-
-#### Frontend
-
-Execute all frontend tests
-
-```bash
-yarn test
-```
-
-Writing & watching frontend tests
-
-- Start watcher: `yarn jest`
-- Jest will run all test files that end with the name ".test.ts"
-
-#### Backend
-
-```bash
-# Run Golang tests using sqlite3 as database (default)
-go test ./pkg/...
-
-# Run Golang tests using mysql as database - convenient to use /docker/blocks/mysql_tests
-GRAFANA_TEST_DB=mysql go test ./pkg/...
-
-# Run Golang tests using postgres as database - convenient to use /docker/blocks/postgres_tests
-GRAFANA_TEST_DB=postgres go test ./pkg/...
-```
-
-#### End-to-end
-
-Execute all end-to-end tests
-
-```bash
-yarn e2e-tests
-```
-
-Execute all end-to-end tests using using a specific url
-
-```bash
-ENV BASE_URL=http://localhost:3333 yarn e2e-tests
-```
-
-Debugging all end-to-end tests (BROWSER=1 will start the browser and SLOWMO=1 will delay each puppeteer operation by 100ms)
-
-```bash
-ENV BROWSER=1 SLOWMO=1 yarn e2e-tests
-```
-
-### Datasource and dashboard provisioning
-
-[Here](https://github.com/grafana/grafana/tree/master/devenv) you can find helpful scripts and docker-compose setup
-that will populate your dev environment for quicker testing end experimenting.

+# Communication
+
+Grafana uses a _bus_ to pass messages between different parts of the application. All communication over the bus happens synchronously.
+
+There are three types of messages: _events_, _commands_, and _queries_.
+
+## Events
+
+An event is something that happened in the past. Since an event has already happened, you can't change it. Instead, you can react to events by triggering additional application logic to be run, whenever they occur.
+
+> Because they happened in the past, event names are written in past tense, such as `UserCreated`, and `OrgUpdated`.
+
+### Subscribe to an event
+
+In order to react to an event, you first need to _subscribe_ to it. 
+
+To subscribe to an event, register an _event listener_ in the service's `Init` method:
+
+```go
+func (s *MyService) Init() error {
+    s.bus.AddEventListener(s.UserCreated)
+    return nil
+}
+
+func (s *MyService) UserCreated(event *events.UserCreated) error {
+    // ...
+}
+```
+
+**Tip:** Browse the available events in the `events` package.
+
+### Publish an event
+
+If you want to let other parts of the application react to changes in a service, you can publish your own events:
+
+```go
+event := &events.StickersSentEvent {
+    UserID: "taylor",
+    Count:   1,
+}
+if err := s.bus.Publish(event); err != nil {
+    return err
+}
+```
+
+## Commands
+
+A command is a request for an action to be taken. Unlike an event's fire-and-forget approach, a command can fail as it is handled. The handler will then return an error.
+
+> Because we request an operation to be performed, command are written in imperative mood, such as `CreateFolderCommand`, and `DeletePlaylistCommand`.
+
+### Dispatch a command
+
+To dispatch a command, pass the object to the `Dispatch` method:
+
+```go
+cmd := &models.SendStickersCommand {
+    UserID: "taylor",
+    Count: 1,
+}
+if err := s.bus.Dispatch(cmd); err != nil {
+  if err == bus.ErrHandlerNotFound {
+    return nil
+  }
+  return err
+}
+```
+
+**Note:** `Dispatch` will return an error if no handler is registered for that command.
+
+**Tip:** Browse the available commands in the `models` package.
+
+### Handle commands
+
+Let others parts of the application dispatch commands to a service, by registering a _command handler_:
+
+To handle a command, register a command handler in the `Init` function.
+
+```go
+func (s *MyService) Init() error {
+    s.bus.AddHandler(s.SendStickers)
+    return nil
+}
+
+func (s *MyService) SendStickers(cmd *models.SendStickersCommand) error {
+    // ...
+}
+```
+
+**Note:** The handler method may return an error if unable to complete the command.
+
+## Queries
+
+A command handler can optionally populate the command sent it. This pattern is commonly used to implement _queries_.
+
+### Making a query
+
+To make a query, dispatch the query instance just like you would a command. When the `Dispatch` method returns, the `Results` field contains the result of the query.
+
+```go
+query := &models.FindDashboardQuery{
+    ID: "foo",
+}
+if err := bus.Dispatch(query); err != nil {
+    return err
+}
+// The query now contains a result.
+for _, item := range query.Results {
+    // ...
+}
+```
+
+### Return query results
+
+To return results for a query, set any of the fields on the query argument before returning:
+
+```go
+func (s *MyService) FindDashboard(query *models.FindDashboardQuery) error {
+    // ...
+    query.Result = dashboard
+    return nil
+}
+```

+# Database
+
+Grafana uses a database to persist settings between restarts. In fact, if you don't specify one, Grafana creates a [SQLite3](https://www.sqlite.org/) database file on your local disk. This guide explains how to store and retrieve data from the database.
+
+Grafana supports the [following databases](https://grafana.com/docs/installation/requirements/#database):
+
+- [MySQL](https://www.mysql.com/)
+- [PostgreSQL](https://www.postgresql.org/)
+- [SQLite3](https://www.sqlite.org/)
+
+Grafana uses the [XORM](https://xorm.io) framework for persisting objects to the database. For more information on how to use XORM, refer to the [documentation](http://gobook.io/read/github.com/go-xorm/manual-en-US/).
+
+[Services](services.md) don't use XORM directly. Instead, services use the _SQL store_, a special type of service that provides an abstraction for the database layer. There are two ways of using the `sqlstore`: using `sqlstore` handlers, and using the `SqlStore` instance.
+
+## `sqlstore` handlers
+
+> **Deprecated:** We are deprecating `sqlstore` handlers in favor of using the `SqlStore` object directly in each service. Since most services still use the `sqlstore` handlers, we still want to explain how they work.
+
+The `sqlstore` package allows you to register [command handlers](communication.md#handle-commands) that either store, or retrieve objects from the database. `sqlstore` handlers are similar to services:
+
+- [Services](services.md) are command handlers that _contain business logic_.
+- `sqlstore` handlers are command handlers that _access the database_.
+
+### Register a `sqlstore` handler
+
+> **Deprecated:** Refer to the [deprecation note for `sqlstore` handlers](#sqlstore-handlers).
+
+To register a handler:
+
+- Create a new file `myrepo.go` in the `sqlstore` package.
+- Create a [command handler](communication.md#handle-commands).
+- Register the handler in the `init` function:
+
+```go
+func init() {
+    bus.AddHandler("sql", DeleteDashboard)
+}
+
+func DeleteDashboard(cmd *models.DeleteDashboardCommand) error {
+    return inTransaction(func(sess *DBSession) error {
+        _, err := sess.Exec("DELETE FROM dashboards WHERE dashboard_id=?", cmd.DashboardID)
+        return err
+    })
+}
+```
+
+Here, `inTransaction` is a helper function in the `sqlstore` package that provides a session, that lets you execute SQL statements.
+
+## `SqlStore`
+
+As opposed to a `sqlstore` handler, the `SqlStore` is a service itself. The `SqlStore` has the same responsibility however: to store and retrieve objects, to and from the database.
+
+To use the `SqlStore`, inject the `SQLStore` in your service struct:
+
+```go
+type MyService struct {
+    SQLStore *sqlstore.SqlStore `inject:""`
+}
+```
+
+You can now make SQL queries in any of your [command handlers](communication.md#handle-commands) or [event listeners](communication.md#subscribe-to-an-event):
+
+```go
+func (s *MyService) DeleteDashboard(cmd *models.DeleteDashboardCommand) error {
+    if err := s.SQLStore.WithDbSession(ctx, func(sess *sqlstore.DBSession) error {
+        _, err := sess.Exec("DELETE FROM dashboards WHERE dashboard_id=?", cmd.DashboardID)
+        return err
+    })
+}
+```
+
+For transactions, use the `WithTransactionalDbSession` method instead.
+
+## Migrations
+
+As Grafana evolves, it becomes necessary to create _schema migrations_ for one or more database tables.
+
+To see all the types of migrations you can add, refer to [migrations.go](/pkg/services/sqlstore/migrator/migrations.go).
+
+Before you add a migration, make sure that you:
+
+- Never change a migration that has been committed and pushed to master.
+- Always add new migrations, to change or undo previous migrations.
+
+Add a migration using one of the following methods:
+
+- Add migrations in the `migrations` package.
+- Implement the `DatabaseMigrator` for the service.
+
+**Important:** If there are previous migrations for a service, use that method. By adding migrations using both methods, you risk running migrations in the wrong order.
+
+### Add migrations in `migrations` package
+
+Most services have their migrations located in the [migrations](/pkg/services/sqlstore/migrations/migrations.go) package.
+
+To add a migration:
+
+- Open the [migrations.go](/pkg/services/sqlstore/migrations/migrations.go) file.
+- In the `AddMigrations` function, find the `addXxxMigration` function for the service you want to create a migration for.
+- At the end of the `addXxxMigration` function, register your migration:
+
+[Example](https://github.com/grafana/grafana/blob/00d0640b6e778ddaca021670fe851fe00982acf2/pkg/services/sqlstore/migrations/migrations.go#L55-L70)
+
+### Implement `DatabaseMigrator`
+
+During initialization, SQL store queries the service registry, and runs migrations for every service that implements the [DatabaseMigrator](https://github.com/grafana/grafana/blob/44c2007498c76c2dbb48e8366b4af410f1ee1b98/pkg/registry/registry.go#L101-L106) interface.
+
+To add a migration:
+
+- If needed, add the `AddMigration(mg *migrator.Migrator)` method to the service.
+- At the end of the `AddMigration` method, register your migration:
+
+```go
+func (s *MyService) AddMigration(mg *migrator.Migrator) {
+    // ...
+
+    mg.AddMigration("Add column age", NewAddColumnMigration(table, &Column{
+        Name:     "age",
+        Type:     migrator.DB_BigInt,
+        Nullable: true,
+    }))
+}
+```

+# Services
+
+A Grafana _service_ encapsulates and exposes application logic to the rest of the application, through a set of related operations. 
+
+Before a service can start communicating with the rest of Grafana, it needs to be registered in the _service registry_.
+
+The service registry keeps track of all available services during runtime. On start-up, Grafana uses the registry to build a dependency graph of services, a _service graph_.
+
+Even though the services in Grafana do different things, they share a number of patterns. To better understand how a service works, let's build one from scratch!
+
+## Create a service
+
+To start building a service:
+
+- Create a new Go package `mysvc` in the [pkg/services](/pkg/services) directory.
+- Create a `service.go` file inside your new directory.
+
+All services need to implement the [Service](https://godoc.org/github.com/grafana/grafana/pkg/registry#Service) interface:
+
+```go
+type MyService struct {
+}
+
+func (s *MyService) Init() error {
+    return nil
+}
+```
+
+The `Init` method is used to initialize and configure the service to make it ready to use. Services that return an error halt Grafana's startup process and cause the error to be logged as it exits.
+
+## Register a service
+
+Every service needs to be registered with the application for it to be included in the service graph.
+
+To register a service, call the `registry.RegisterService` function in an `init` function within your package.
+
+```go
+func init() {
+    registry.RegisterService(&MyService{})
+}
+```
+
+`init` functions are only run whenever a package is imported, so we also need to import the package in the application. In the `server.go` file under `pkg/cmd/grafana-server`, import the package we just created:
+
+```go
+import _ "github.com/grafana/grafana/pkg/services/mysvc"
+```
+
+## Dependencies
+
+Grafana uses the [inject](https://github.com/facebookgo/inject) package to inject dependencies during runtime. 
+
+For example, to access the [bus](communication.md), add it to the `MyService` struct:
+
+```go
+type MyService struct {
+    Bus bus.Bus `inject:""`
+}
+```
+
+You can also inject other services in the same way:
+
+```go
+type MyService struct {
+    Service other.Service `inject:""`
+}
+```
+
+**Note:** Any injected dependency needs to be an exported field. Any unexported fields result in a runtime error.

+# Create a pull request
+
+We're excited that you're considering making a contribution to the Grafana project! This document guides you through the process of creating a [pull request](https://help.github.com/en/articles/about-pull-requests/).
+
+## Before you begin
+
+We know you're excited to create your first pull request. Before we get started, read these resources first:
+
+- Learn how to start [Contributing to Grafana](/CONTRIBUTING.md).
+- Make sure your code follows the relevant [style guides](/contribute/style-guides).
+
+## Your first pull request
+
+If this is your first time contributing to an open-source project on GitHub, make sure you read about [Creating a pull request](https://help.github.com/en/articles/creating-a-pull-request).
+
+To increase the chance of having your pull request accepted, make sure your pull request follows these guidelines:
+
+- Title and description matches the implementation.
+- Commits within the pull request follow the [Formatting guidelines](#Formatting-guidelines). 
+- The pull request closes one related issue.
+- The pull request contains necessary tests that verify the intended behavior.
+- If your pull request has conflicts, rebase your branch onto the master branch.
+
+If the pull request fixes a bug:
+
+- The pull request description must include `Closes #<issue number>` or `Fixes #<issue number>`.
+- To avoid regressions, the pull request should include tests that replicate the fixed bug.
+
+### Frontend-specific guidelines
+
+Pull requests for frontend contributions must:
+
+- Use [Emotion](/contribute/style-guides/styling.md) for styling.
+- Not increase the Angular code base.
+- Not use `any` or `{}` without reason.
+- Not contain large React components that could easily be split into several smaller components.
+- Not contain backend calls directly from components—use actions and Redux instead.
+
+Pull requests for Redux contributions must:
+
+- Use the `actionCreatorFactory` and `reducerFactory` helpers instead of traditional switch statement reducers in Redux. Refer to [Redux framework](/contribute/style-guides/redux.md) for more details.
+- Use `reducerTester` to test reducers. Refer to [Redux framework](/contribute/style-guides/redux.md) for more details.
+- Not contain code that mutates state in reducers or thunks.
+- Not contain code that accesses the reducers state slice directly. Instead, the code should use state selectors to access state.
+
+## Code review
+
+Once you've created a pull request, the next step is to have someone review your change. A review is a learning opportunity for both the reviewer and the author of the pull request.
+
+If you think a specific person needs to review your pull request, then you can tag them in the description or in a comment. Tag a user by typing the `@` symbol followed by their GitHub username.
+
+We recommend that you read [How to do a code review](https://google.github.io/eng-practices/review/reviewer/) to learn more about code reviews.
+
+## Formatting guidelines
+
+A well-written pull request minimizes the time to get your change accepted. These guidelines help you write good commit messages and descriptions for your pull requests.
+
+### Commit message format
+
+Grafana uses the guidelines for commit messages outlined in [How to Write a Git Commit Message](https://chris.beams.io/posts/git-commit/), with the following additions:
+
+- Subject line must begin with the _area_ of the commit.
+- A footer in the form of an optional [keyword and issue reference](https://help.github.com/en/articles/closing-issues-using-keywords).
+
+#### Area
+
+The area should use upper camel case, e.g. UpperCamelCase.
+
+Prefer using one of the following areas:
+
+- **Build:** Changes to the build system, or external dependencies.
+- **Chore:** Changes that don't affect functionality.
+- **Dashboard:** Changes to the Dashboard feature.
+- **Docs:** Changes to documentation.
+- **Explore:** Changes to the Explore feature.
+- **Plugins:** Changes to any of the plugins.
+
+For changes to data sources, the area should be the name of the data source, e.g., AzureMonitor, Graphite, and Prometheus.
+
+For changes to panels, the area should be the name of the panel, suffixed with Panel, e.g., GraphPanel, SinglestatPanel, and TablePanel.
+
+**Examples**
+
+- `Build: Support publishing MSI to grafana.com`
+- `Explore: Add Live option for supported data sources`
+- `GraphPanel: Fix legend sorting issues`
+- `Docs: Changed url to URL in all documentation files`
+
+### Pull request titles
+
+The Grafana team _squashes_ all commits into one when we accept a pull request. The title of the pull request becomes the subject line of the squashed commit message. We still encourage contributors to write informative commit messages, as they becomes a part of the Git commit body.
+
+We use the pull request title when we generate change logs for releases. As such, we strive to make the title as informative as possible.
+
+Make sure that the title for your pull request uses the same format as the subject line in the commit message.

+# Developer guide
+
+This guide helps you get started developing Grafana.
+
+Before you begin, you might want to read [How to contribute to Grafana as a junior dev](https://medium.com/@ivanahuckova/how-to-contribute-to-grafana-as-junior-dev-c01fe3064502) by [Ivana Huckova](https://medium.com/@ivanahuckova).
+
+
+## Dependencies
+
+Make sure you have the following dependencies installed before setting up your developer environment:
+
+- [Git](https://git-scm.com/)
+- [Go](https://golang.org/dl/) (see [go.mod](../go.mod#L3) for minimum required version)
+- [Node.js (Long Term Support)](https://nodejs.org)
+- [Yarn](https://yarnpkg.com)
+
+### macOS
+
+We recommend using [Homebrew](https://brew.sh/) for installing any missing dependencies:
+
+```
+brew install git
+brew install go
+brew install node
+
+npm install -g yarn
+```
+
+## Download Grafana
+
+We recommend using Go to download the source code for the Grafana project:
+
+1. Add `export GOPATH=$HOME/go/` to the bottom of your `$HOME/.bash_profile`.
+1. Open a terminal and run `go get github.com/grafana/grafana` in your terminal. This command downloads, and installs Grafana to your `$GOPATH`.
+1. Open `$GOPATH/src/github.com/grafana/grafana` in your favorite code editor.
+
+## Build Grafana
+
+Grafana consists of two components; the _frontend_, and the _backend_.
+
+### Frontend
+
+Before we can build the frontend assets, we need to install the dependencies:
+
+```
+yarn install --pure-lockfile
+```
+
+After the command has finished, we can start building our source code:
+
+```
+yarn start
+```
+
+Once `yarn start` has built the assets, it will continue to do so whenever any of the files change. This means you don't have to manually build the assets whenever every time you change the code.
+
+Next, we'll build the web server that will serve the frontend assets we just built.
+
+### Backend
+
+Build and run the backend by running `make run` in the root directory of the repository. This command compiles the Go source code and starts a web server.
+
+> Are you having problems with [too many open files](#troubleshooting)?
+
+By default, you can access the web server at `http://localhost:3000/`.
+
+Log in using the default credentials:
+
+| username | password |
+| -------- | -------- |
+| `admin`  | `admin`  |
+
+When you log in for the first time, Grafana asks you to change your password.
+
+#### Building on Windows
+
+The Grafana backend includes Sqlite3 which requires GCC to compile. So in order to compile Grafana on Windows you need to install GCC. We recommend [TDM-GCC](http://tdm-gcc.tdragon.net/download).
+
+## Test Grafana
+
+The test suite consists of three types of tests: _Frontend tests_, _backend tests_, and _end-to-end tests_.
+
+### Run frontend tests
+
+We use [jest](https://jestjs.io/) for our frontend tests. Run them using Yarn:
+
+```
+yarn jest
+```
+
+### Run backend tests
+
+If you're developing for the backend, run the tests with the standard Go tool:
+
+```
+go test -v ./pkg/...
+```
+
+### Run end-to-end tests
+
+The end to end tests in Grafana use [Cypress](https://www.cypress.io/) to run automated scripts in a headless Chromium browser. Read more about our [e2e framework](/contribute/style-guides/e2e.md). 
+
+To run the tests:
+
+```
+yarn e2e-tests
+```
+
+By default, the end-to-end tests assumes Grafana is available on `localhost:3000`. To use a specific URL, set the `BASE_URL` environment variable:
+
+```
+BASE_URL=http://localhost:3333 yarn e2e-tests
+```
+
+To follow the tests in the browser while they're running, use the `yarn e2e-tests:debug` instead.
+
+```
+yarn e2e-tests:debug
+```
+
+## Configure Grafana for development
+
+The default configuration, `grafana.ini`, is located in the `conf` directory. 
+
+To override the default configuration, create a `custom.ini` file in the `conf` directory. You only need to add the options you wish to override.
+
+Enable the development mode, by adding the following line in your `custom.ini`:
+
+```
+app_mode = development
+```
+
+
+### Add data sources
+
+By now, you should be able to build and test a change you've made to the Grafana source code. In most cases, you need to add at least one data source to verify the change.
+
+To set up data sources for your development environment, go to the [devenv](/devenv) directory in the Grafana repository:
+
+```
+cd devenv
+```
+
+Run the `setup.sh` script to set up a set of data sources and dashboards in your local Grafana instance. The script creates a set of data sources called **gdev-\<type\>**, and a set of dashboards located in a folder called **gdev dashboards**.
+
+Some of the data sources require databases to run in the background.
+
+Installing and configuring databases can be a tricky business. Grafana uses [Docker](https://docker.com) to make the task of setting up databases a little easier. Make sure you [install Docker](https://docs.docker.com/docker-for-mac/install/) before proceeding to the next step.
+
+In the root directory of your Grafana repository, run the following command:
+
+```
+make devenv sources=influxdb,loki
+```
+
+The script generates a Docker Compose file with the databases you specify as `sources`, and runs them in the background.
+
+See the repository for all the [available data sources](/devenv/docker/blocks). Note that some data sources have specific Docker images for macOS, e.g. `prometheus_mac`.
+
+## Build a Docker image
+
+To build a Docker image, run:
+
+```
+make build-docker-full
+```
+
+The resulting image will be tagged as grafana/grafana:dev.
+
+**Note:** If you've already set up a local development environment, and you're running a `linux/amd64` machine, you can speed up building the Docker image:
+
+1. Build the frontend: `go run build.go build-frontend`.
+1. Build the Docker image: `make build-docker-dev`.
+
+**Note:** If you are using Docker for macOS, be sure to set the memory limit to be larger than 2 GiB. Otherwise `grunt build` may fail. The memory limit settings are available under **Docker Desktop** -> **Preferences** -> **Advanced**.
+
+## Troubleshooting
+
+Are you having issues with setting up your environment? Here are some tips that might help.
+
+### Too many open files when running `make run`
+
+Depending on your environment, you may have to increase the maximum number of open files allowed.
+
+To see how many open files are allowed, run:
+
+```
+ulimit -a
+```
+
+To change the number of open files allowed, run:
+
+```
+ulimit -S -n 2048
+```
+
+The number of files needed may be different on your environment. To determine the number of open files needed by `make run`, run:
+
+```
+find ./conf ./pkg ./public/views | wc -l
+```
+
+Another alternative is to limit the files being watched. The directories that are watched for changes are listed in the `.bra.toml` file in the root directory.

+# Backend style guide
+
+Grafanas backend has been developed for a long time with a mix of code styles.  This guide explains how we want to write Go code in the future.
+
+Unless stated otherwise, use the guidelines listed in the following articles:
+
+- [Effective Go](https://golang.org/doc/effective_go.html)
+- [Code Review Comments](https://github.com/golang/go/wiki/CodeReviewComments)
+- [Go: Best Practices for Production Environments](http://peter.bourgon.org/go-in-production/#formatting-and-style)
+
+## Linting and formatting
+
+To ensure consistency across the Go codebase, we require all code to pass a number of linter checks.
+
+We use the standard following linters:
+
+- [gofmt](https://golang.org/cmd/gofmt/)
+- [golint](https://github.com/golang/lint)
+- [go vet](https://golang.org/cmd/vet/)
+
+In addition to the standard linters, we also use:
+
+- [revive](https://revive.run/) with a [custom config](https://github.com/grafana/grafana/blob/master/conf/revive.toml)
+- [GolangCI-Lint](https://github.com/golangci/golangci-lint)
+- [gosec](https://github.com/securego/gosec)
+
+To run all linters, use the `lint-go` Makefile target:
+
+```bash
+make lint-go
+```
+
+## Testing
+
+We value clean and readable code, that is loosely coupled and covered by unit tests. This makes it easier to collaborate and maintain the code.
+
+Tests must use the standard library, `testing`. For assertions, prefer using [testify](https://github.com/stretchr/testify).
+
+The majority of our tests uses [GoConvey](http://goconvey.co/) but that's something we want to avoid going forward.
+
+In the `sqlstore` package we do database operations in tests and while some might say that's not suited for unit tests. We think they are fast enough and provide a lot of value.
+
+## General guidelines
+
+- Avoid using import aliases, e.g. `import m "github.com/grafana/grafana/pkg/models"`.

+# Documentation style guide
+
+This style guide applies to all documentation created for Grafana products.
+
+## Contributing
+
+The *Documentation style guide* is a living document. Add to it whenever a style decision is made or a question is answered regarding style, grammar, or word choice.
+
+## Published guides
+
+For all items not covered in this guide, refer to the [Microsoft Style Guide](https://docs.microsoft.com/en-us/style-guide/welcome/) and the [Chicago Manual of Style](https://www.chicagomanualofstyle.org/home.html).
+
+## Spelling
+
+The [codespell](https://github.com/codespell-project/codespell) tool is run for every change to catch common misspellings.
+
+## Grafana-specific style
+
+The following sections provide general guidelines on topics specific to Grafana documentation. Note that for the most part, these are *guidelines*, not rigid rules. If you have questions, ask in the #docs channel of Grafana Slack.
+
+### General
+
+* Use active voice. Avoid passive voice.
+  - Passive: The heatmap visualization is displayed.
+  - Active: Grafana displays the heatmap visualization.
+* Write in the imperative second person. Examples: You can write a query. Click the panel. Close the window.
+* Write in present tense.
+  - Not: The panel will open.
+  - Use: The panel opens. Grafana opens the panel.
+* Do not use an ampersand (&) as an abbreviation for "and." 
+  - **Exceptions:** If an ampersand is used in the Grafana UI, then match the UI.
+
+### File naming conventions
+
+- Files that are displayed in the help system should have names that are all lowercase, no spaces. Use hyphens instead of spaces. Example: glossary.md
+- Documentation file names should match the title. **Note:** This only applies to new files at this time. Do not change the names of older files unless directed to do so.
+- Internal reference file names should be all uppercase except the file extension. Example: CONTRIBUTING.md
+
+### Headings
+
+* Write headings in sentence case, not title case.
+  - This is sentence case
+  - This Is Title Case
+* Task topic headings start with a verb.
+  - Write a query. Create a dashboard.
+* Concept and reference topic headings should be nouns or gerunds. Examples: Contributing to docs, Visualizations, Style guide
+* Avoid following one heading with another heading.
+* Avoid skipping heading levels. For example, an h1 should be followed by an h2 rather than an h3.
+* Avoid having just one lower-level heading. For example, h1, h2, h2, h3, h3, h2 is a good order. Do no go h1, h2, h3, h2, h3, h2.
+* Don't include parenthetical words like (Important!) in headings.
+
+### Images
+
+* Preferred format is .png
+* File extension should be all lowercase.
+* Preferred DPI is 72.
+* Assume all graphics will be exclusively viewed on the web.
+* Maximum image size is 3840px X 2160px.
+* Screenshots should be readable, but not too large.
+
+### Capitalization
+
+* Grafana, Loki, and Prometheus are always capitalized unless part of a code block.
+* API names are always Title Case, followed by "API"—for example, "Dashboard Permissions API"
+* Git is always capitalized, unless part of a code block.
+* Abbreviations are always capitalized (such as API, HTTP, ID, JSON, SQL, or URL) unless they are part of a code block.
+* Menu and submenu titles always use sentence case: capitalize the first word, and lowercase the rest.
+  - "Dashboards" when referring to the submenu title.
+  - "Keyboard shortcuts" when referring to the submenu topic.
+* Generic and plural versions are always lowercase.
+  - Lowercase "dashboard" when referring to a dashboard generally.
+  - Lowercase "dashboards" when referring to multiple dashboards.
+* **Exceptions:** If a term is lowercased in the Grafana UI, then match the UI.
+
+### Links and references
+
+When referencing another document, use "Refer to" rather than alternatives such as "See" or "Check out."
+
+Always give the reader some idea of what to expect in the reference. Avoid blind references, such as, "Refer to [this file](link)."
+
+When possible, use the exact title of the page or section you are linking to as the link text.
+
+**Example**
+Refer to the [Documentation style guide](documentation-style-guide.md) for information about word usage and capitalization guidelines.
+
+### Command line examples
+
+* Do not assume everyone is using Linux. Make sure instructions include enough information for Windows and Mac users to successfully complete procedures.
+
+* Do not add `$` before commands. Make it easy for users to copy and paste commands.
+
+  * **Wrong:** `$ sudo yum install grafana`
+  * **Right:** `sudo yum install grafana`
+
+* Include `sudo` before commands that require `sudo` to work.
+
+For terminal examples and Grafana configuration, use a `bash` code block:
+```bash
+sudo yum install grafana
+```
+For HTTP request/response, use an `http` code block:
+```http
+GET /api/dashboards/id/1/permissions HTTP/1.1
+Accept: application/json
+Content-Type: application/json
+Authorization: Bearer eyJrIjoiT0tTcG1pUlY2RnVKZTFVaDFsNFZXdE9ZWmNrMkZYbk
+```
+
+### Word usage
+
+Grafana products has some words, abbreviations, and slang particular to this discourse community.
+
+#### checkout, check out
+
+Two words if used as a verb, one word if used as a noun.
+
+**Examples**
+
+* Check out these new features!
+* Proceed to checkout.
+
+#### data source
+
+Two words, not one
+
+**Exceptions:**
+* "datasource" used as an identifier
+* "datasource" in a URL
+* Use "data source" instead of "datasource" unless used as an identifier, in code, or as part of a URL.
+* Spell out "repository" and avoid the shorter "repo."
+* Use "Unix" as the preferred spelling (as opposed to "UNIX", or "unix") when referring to the family of operating systems.
+
+#### display (verb)
+
+*Display* is a transitive verb, which means it always needs a direct object.
+* Correct, active voice: Grafana displays your list of active alarms.
+* Correct, but passive voice: Your list of active alarms is displayed.
+* Incorrect: The list of active alarms displays.
+
+#### open source, open-source
+
+Do not hyphenate when used as an adjective unless the lack of hyphen would cause confusion. For example: _Open source software design is the most open open-source system I can imagine._ 
+
+Do not hyphenate when it is used as a noun. For example: _Open source is the best way to develop software._
+
+#### setup, set up
+
+Two words if used as a verb, one word if used as a noun.
+
+**Examples**
+
+* Set up the workspace.
+* Initial setup might take five minutes.

+# End to end test framework
+Grafana Labs uses a minimal home grown solution built on top of Cypress for our end to end (e2e) tests.
+
+## Basic concepts
+Here is a good introduction to e2e best practices: https://martinfowler.com/bliki/PageObject.html.
+- `Selector`: A unique identifier that is used from the e2e framework to retrieve an element from the Browser
+- `Page`: An abstraction for an object that contains one or more `Selectors`
+- `Flow`: An abstraction that contains a sequence of actions on one or more `Pages` that can be reused and shared between tests
+
+## Basic example
+Let's start with a simple example with a single selector. For simplicity, all examples are in JSX.
+
+In our example app, we have an input that we want to type some text into during our e2e test.
+```jsx harmony
+<div>
+    <input type="text" className="gf-form-input login-form-input"/>
+</div>
+```
+
+We could define a selector using `JQuery` [type selectors](https://api.jquery.com/category/selectors/) with a string like `'.gf-form-input.login-form-input'` but that would be brittle as style changes occur frequently. Furthermore there is nothing that signals to future developers that this input is part of an e2e test.
+
+At Grafana, we use `aria-label` as our preferred way of defining selectors instead of `data-*` attributes. This also aids in accessibility.
+Let's add a descriptive `aria-label` to our simple example.
+```jsx harmony
+<div>
+    <input type="text" className="gf-form-input login-form-input" aria-label="Username input field"/>
+</div>
+```
+
+Now that we added the `aria-label` we suddenly get more information about this particular field. It's an input field that represents a username, but there it's still not really signaling that it's part of an e2e test.
+
+The next step is to create a `Page` representation in our e2e test framework to glue the test with the real implementation using the `pageFactory` function. For that function we can supply a `url` and `selectors` like in the example below:
+```typescript
+export const Login = pageFactory({
+  url: '/login', // used when called from Login.visit()
+  selectors: {
+    username: 'Username input field', // used when called from Login.username().type('Hello World')
+  },
+});
+```
+
+The next step is to add the `Login` page to the exported const `Pages` in `packages/grafana-e2e/src/pages/index.ts` so that it appears when we type `e2e.pages` in our IDE.
+```ecmascript 6
+export const Pages = {
+  Login,
+  ...,
+  ...,
+  ...,
+};
+
+```
+Now that we have a `Page` called `Login` in our `Pages` const we can use that to add a selector in our html like shown below and now this really signals to future developers that it is part of an e2e test.
+```jsx harmony
+<div>
+    <input type="text" className="gf-form-input login-form-input" aria-label={e2e.pages.Login.selectors.username}/>
+</div>
+```
+
+The last step in our example is to use our `Login` page as part of a test. The `pageFactory` function we used before gives us two things:
+- The `url` property is used whenever we call the `visit` function and is equivalent to the Cypress function [cy.visit()](https://docs.cypress.io/api/commands/visit.html#Syntax).
+> Best practice after calling `visit` is to always call `should` on a selector to prevent flaky tests when you try to access an element that isn't ready. For more information, refer to [Commands vs. assertions](https://docs.cypress.io/guides/core-concepts/retry-ability.html#Commands-vs-assertions).
+- Any defined selector in the `selectors` property can be accessed from the `Login` page by invoking it. This is equivalent to the result of the Cypress function [cy.get(...)](https://docs.cypress.io/api/commands/get.html#Syntax).
+```ecmascript 6
+describe('Login test', () => {
+  it('Should pass', () => {
+    e2e.pages.Login.visit();
+    // To prevent flaky tests, always do a .should on any selector that you expect to be in the DOM.
+    // Read more here: https://docs.cypress.io/guides/core-concepts/retry-ability.html#Commands-vs-assertions
+    e2e.pages.Login.username().should('be.visible');
+    e2e.pages.Login.username().type('admin');
+  });
+});
+```
+
+## Advanced example
+Let's take a look at an example that uses the same `selector` for multiple items in a list for instance. In this example app we have a list of data sources that we want to click on during an e2e test.
+
+```jsx harmony
+<ul>
+  {dataSources.map(dataSource => (
+    <li className="card-item-wrapper" key={dataSource.id}>
+      <a className="card-item" href={`datasources/edit/${dataSource.id}`}>
+        <div className="card-item-name">
+          {dataSource.name}
+        </div>
+      </a>
+    </li>
+  ))}
+</ul>
+```
+```
+
+Just as before in the basic example we'll start by creating a page abstraction using the `pageFactory` function:
+```typescript
+export const DataSources = pageFactory({
+  url: '/datasources',
+  selectors: {
+    dataSources: (dataSourceName: string) => `Data source list item ${dataSourceName}`,
+  },
+});
+```
+You might have noticed that instead of a simple `string` as the `selector`, we're using a `function` that takes a string parameter as an argument and returns a formatted string using the argument.
+
+Just as before we need to add the `DataSources` page to the exported const `Pages` in `packages/grafana-e2e/src/pages/index.ts`.
+
+The next step is to use the `dataSources` selector function as in our example below:
+```jsx harmony
+<ul>
+  {dataSources.map(dataSource => (
+    <li className="card-item-wrapper" key={dataSource.id}>
+      <a className="card-item" href={`datasources/edit/${dataSource.id}`}>
+        <div className="card-item-name" aria-label={e2e.pages.DataSources.selectors.dataSources(dataSource.name)}>
+          {dataSource.name}
+        </div>
+      </a>
+    </li>
+  ))}
+</ul>
+```
+
+When this list is rendered with the data sources with names `A`, `B`, `C` the resulting html would become:
+```jsx harmony
+<div class="card-item-name" aria-label="Data source list item A">
+ A
+</div>
+...
+<div class="card-item-name" aria-label="Data source list item B">
+ B
+</div>
+...
+<div class="card-item-name" aria-label="Data source list item C">
+ C
+</div>
+```
+
+Now we can write our test. The one thing that differs from the `Basic example` is that we pass in which data source we want to click on as an argument to the selector function:
+> Best practice after calling `visit` is to always call `should` on a selector to prevent flaky tests when you try to access an element that isn't ready. For more information, refer to [Commands vs. assertions](https://docs.cypress.io/guides/core-concepts/retry-ability.html#Commands-vs-assertions).
+```ecmascript 6
+describe('List test', () => {
+  it('Clicking on data source named B', () => {
+    e2e.pages.DataSources.visit();
+    // To prevent flaky tests, always do a .should on any selector that you expect to be in the DOM.
+    // Read more here: https://docs.cypress.io/guides/core-concepts/retry-ability.html#Commands-vs-assertions
+    e2e.pages.DataSources.dataSources('B').should('be.visible');
+    e2e.pages.DataSources.dataSources('B').click();
+  });
+});
+```
+
+
+## Debugging PhantomJS image rendering
+
+There is no easy or comprehensive way to debug PhantomJS smoke test (image rendering) failures. However, PhantomJS exposes remote debugging interface which can give you a sense of what is going wrong in the smoke test. Before performing the steps described below make sure your local Grafana instance is running:
+
+1. Go to `tools/phantomjs` directory
+2. Execute `phantomjs` binary against `render.js` file: `./phantomjs --remote-debugger-port=9009 --remote-debugger-autorun=yes ./render.js url="http://localhost:3000"`
+3. In your browser navigate to `http://localhost:9009/`
+4. Select `http://localhost:3000/login` from the list. You will get access to Webkit's inspector to see the console's output from the smoke test.
+
+The method described above is not perfect, but is helpful to evaluate smoke tests breaking due to bundle errors.

+# Redux framework
+
+Grafana uses [Redux Toolkit](https://redux-toolkit.js.org/) to handle Redux boilerplate code.
+> Some of our Reducers are used by Angular and therefore state is to be considered as mutable for those reducers.
+
+## Test functionality
+
+### reducerTester
+
+Fluent API that simplifies the testing of reducers
+
+#### Usage
+
+```typescript
+reducerTester()
+  .givenReducer(someReducer, initialState)
+  .whenActionIsDispatched(someAction('reducer tests'))
+  .thenStateShouldEqual({ ...initialState, data: 'reducer tests' });
+```
+
+#### Complex usage
+Sometimes you encounter a `resulting state` that contains properties that are hard to compare, such as `Dates`, but you still want to compare that other props in state are correct.
+
+Then you can use `thenStatePredicateShouldEqual` function on `reducerTester` that will return the `resulting state` so that you can expect upon individual properties..
+
+```typescript
+reducerTester()
+  .givenReducer(someReducer, initialState)
+  .whenActionIsDispatched(someAction('reducer tests'))
+  .thenStatePredicateShouldEqual(resultingState => {

+
+### thunkTester
+
+Fluent API that simplifies the testing of thunks.
+
+#### Usage
+
+```typescript
+const dispatchedActions = await thunkTester(initialState)
+    .givenThunk(someThunk)
+    .whenThunkIsDispatched(arg1, arg2, arg3);

+# Styling Grafana
+
+## Emotion
+
+[Emotion](https://emotion.sh/docs/introduction) is our default-to-be approach to styling React components. It provides a way for styles to be a consequence of properties and state of a component.
+
+### Usage
+
+#### Basic styling
+
+For styling components use Emotion's `css` function
+
+```tsx
+import { css }  from 'emotion';
+
+
+const ComponentA = () => {
+  return (
+    <div className={css`background: red;`}>
+      As red as you can ge
+    </div>
+  );
+}
+```
+
+#### Styling complex components
+
+In more complex cases, especially when you need to style multiple DOM elements in one component or when your styles that depend on properties and/or state, you should create a helper function that returns an object with desired stylesheet. This function should also be wrapped in `stylesFactory` helper function that will provide basic memoization.
+
+Let's say you need to style a component that has different background depending on the theme:
+
+```tsx
+import { css, cx }  from 'emotion';
+import { GrafanaTheme, useTheme, selectThemeVariant, stylesFactory } from '@grafana/ui';
+
+const getStyles = stylesFactory((theme: GrafanaTheme) => {
+  const backgroundColor = selectThemeVariant({ light: theme.colors.red, dark: theme.colors.blue }, theme.type);
+
+  return {
+    wrapper: css`
+      background: ${backgroundColor};
+    `,
+    icon: css`font-size:${theme.typography.size.sm}`;
+  };
+}
+
+const ComponentA = () => {
+  const theme = useTheme();
+  const styles = getStyles(theme);
+
+  return (
+    <div className={styles.wrapper}>
+      As red as you can get
+      <i className={styles.icon} />
+    </div>
+  );
+});
+```
+
+For more information about themes at Grafana please see [themes guide](./themes.md)
+
+#### Composing class names
+
+For class composition use Emotion's `cx` function
+
+```tsx
+import { css, cx }  from 'emotion';
+
+
+interface Props {
+  className?: string;
+}
+
+const ComponentA: React.FC<Props> = ({ className }) => {
+  const finalClassName = cx(
+    className,
+    css`background: red`,
+  )
+
+  return (
+    <div className={finalClassName}>
+      As red as you can ge
+    </div>
+  );
+}
+```

+# Theming Grafana
+
+## Overview
+
+**Themes are implemented in Typescript.** That's because our goal is to share variables between Grafana Typescript code and SASS files. Theme definitions are located in `packages/grafana-ui/src/themes/[default|dark|light].ts` files. `default.ts` file holds common variables like typography and spacing definitions, while `[light|dark].ts` primarily specify colors used in themes.
+
+## Usage
+### Using themes in React components
+
+#### Using `ThemeContext` directly
+
+```tsx
+import { ThemeContext } from '@grafana/ui';
+
+<ThemeContext.Consumer>{theme => <Foo theme={theme} />}</ThemeContext.Consumer>;
+```
+
+or
+
+```tsx
+import React, { useContext } from 'react';
+import { ThemeContext } from '@grafana/ui';
+
+const Foo: React.FunctionComponent<FooProps> = () => {
+  const theme = useContext(ThemeContext);
+
+  // Your component has access to the theme variables now
+}
+
+```
+
+#### Using `withTheme` higher-order component (HOC)
+
+With this method your component will be automatically wrapped in `ThemeContext.Consumer` and provided with current theme via `theme` prop. Component used with `withTheme` must implement `Themeable` interface.
+
+```ts
+import  { ThemeContext, Themeable } from '@grafana/ui';
+
+interface FooProps extends Themeable {}
+
+const Foo: React.FunctionComponent<FooProps> = () => ...
+
+export default withTheme(Foo);
+```
+
+### Test components that use ThemeContext
+
+When implementing snapshot tests for components that use the `withTheme` HOC, the snapshot will contain the entire theme object. Any change to the theme renders the snapshot outdated.
+
+To make your snapshot theme independent, use the `mockThemeContext` helper function:
+
+```tsx
+import { mockThemeContext } from '@grafana/ui';
+import { MyComponent } from './MyComponent';
+
+describe('MyComponent', () => {
+  let restoreThemeContext;
+
+  beforeAll(() => {
+    // Create ThemeContext mock before any snapshot test is executed
+    restoreThemeContext = mockThemeContext({ type: GrafanaThemeType.Dark });
+  });
+
+  afterAll(() => {
+    // Make sure the theme is restored after snapshot tests are performed
+    restoreThemeContext();
+  });
+
+  it('renders correctyl', () => {
+    const wrapper = mount(<MyComponent />)
+    expect(wrapper).toMatchSnapshot();
+  });
+});
+```
+
+### Using themes in Storybook
+
+All stories are wrapped with `ThemeContext.Provider` using global decorator. To render `Themeable` component that's not wrapped by `withTheme` HOC you either create a new component in your story:
+
+```tsx
+// Foo.story.tsx
+const FooWithTheme = withTheme(Foo);
+
+FooStories.add('Story' () => {
+  return <FooWithTheme />
+});
+```
+
+or use `renderComponentWithTheme` helper:
+
+```tsx
+// Bar.story.tsx
+
+BarStories.add('Story' () => {
+  return renderComponentWithTheme(Bar, /* pass props here */)
+});
+```
+
+### Using themes in Angular code
+
+There should be very few cases where theme would be used in Angular context. For this purpose there is a function available that retrieves current theme: `import { getCurrentTheme } from app/core/utils/ConfigProvider`. Angular components should be migrated to React, or if that's not possible at the moment, styled using SASS.
+
+
+## FAQ
+### How can I modify SASS variable files?
+> For the following to apply you need to run `yarn dev` task.
+
+`[_variables|_variables.dark|_variables.light].generated.scss` files are the ones that are referenced in the main SASS files for SASS variables to be available. **These files are automatically generated and should never be modified by hand!**.
+
+#### If you need to modify *SASS variable value* you need to modify corresponding Typescript file that is a source of the variables:
+- `_variables.generated.scss` - modify `grafana-ui/src/themes/default.ts`
+- `_variables.light.generated.scss` - modify `grafana-ui/src/themes/light.ts`
+- `_variables.dark.generated.scss` - modify `grafana-ui/src/themes/dark.ts`
+
+#### If you need to *add new variable* to SASS variables you need to modify corresponding template file:
+- `_variables.generated.scss` - modify `grafana-ui/src/themes/_variables.scss.tmpl.ts`
+- `_variables.light.generated.scss` - modify `grafana-ui/src/themes/_variables.light.scss.tmpl.ts`
+- `_variables.dark.generated.scss` - modify `grafana-ui/src/themes/_variables.dark.scss.tmpl.ts`
+
+
+## Limitations
+### You must ensure ThemeContext provider is available in a React tree
+  By default all react2angular directives have `ThemeContext.Provider` ensured. But, there are cases where we create another React tree via `ReactDOM.render`. This happens in case of graph legend rendering and `ReactContainer` directive. In such cases theme consumption will fail. To make sure theme context is available in such cases, you need to wrap your rendered component with ThemeContext.Provider using `provideTheme` function:
+
+```ts
+// graph.ts
+import { provideTheme } from 'app/core/utils/ConfigProvider';
+
+// Create component with ThemeContext.Provider first.
+// Otherwise React will create new components every time it renders!

+# Triage issues
+
+Triage helps ensure that issues resolve quickly by:
+
+- Ensuring the issue's intent and purpose is conveyed precisely. This is necessary because it can be difficult for an issue to explain how an end user experiences a problem and what actions they took.
+- Giving a contributor the information they need before they commit to resolving an issue.
+- Lowering the issue count by preventing duplicate issues.
+- Streamlining the development process by preventing duplicate discussions.
+
+This document gives you some ideas on what you can do to help. For more information, read more about [how the core Grafana team triage issues](/ISSUE_TRIAGE.md).
+
+## Improve issues
+
+Improve issues by suggesting improvements to the title and description. If you think an issue has formatting issues, bad language, or grammatical errors, post a comment to let the author and maintainers know.
+
+## Report resolved issues
+
+If you think an issue has been resolved, or is no longer relevant, suggest us to close it. Add a comment on the issue, where you explain the reason it should be closed. Make sure to include any related issues and pull requests.
+
+## Investigate issues
+
+Investigate issues that we haven't been able to reproduce yet. In some cases, there are many combinations of panels, dashboards, and data sources that make it difficult for us to reproduce certain issues. Help us by adding more information.
+
+## Vote on issues
+
+Use [GitHub reactions](https://help.github.com/en/articles/about-conversations-on-github#reacting-to-ideas-in-comments) to let us know what's important to you. Vote on bugs if you've experienced the same problem. **Don't vote, or react, by commenting on the issue.**
+
+Read more about [how we prioritize issues](/ISSUE_TRIAGE.md#4-prioritization-of-issues).
+
+## Report duplicates
+
+If you find two issues that describe the same thing, add a comment in one of the issues, with a reference (`#<issue number>`) to the other. Explain why you think the issue is duplicated.
