* 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.
* For changes in the backend, follow the style guides used in Go [Code Review Comments](https://code.google.com/p/go-wiki/wiki/CodeReviewComments) and Peter Bourgon's [Go: Best Practices for Production Environments](http://peter.bourgon.org/go-in-production/#formatting-and-style)
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.
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.
To setup a local development environment we recommend reading [Building Grafana from source](http://docs.grafana.org/project/building_from_source/)
* 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.
* 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.
* Add tests relevant to the fixed bug or new feature.
