We'd love to accept your patches and contributions to this project. There are just a few small guidelines you need to follow.
Contributions to this project must be accompanied by a Contributor License Agreement. You (or your employer) retain the copyright to your contribution, this simply gives us permission to use and redistribute your contributions as part of the project. Head over to https://cla.developers.google.com/ to see your current agreements on file or to sign a new one.
You generally only need to submit a CLA once, so if you've already submitted one (even if it was for a different project), you probably don't need to do it again.
If you've found a issue, please do file a bug for us. We ask that you include some information (included in the new issue template) so that we can reproduce and fix the problem.
Occasionally we'll close issues if they appear stale or are too vague - please don't take this personally! Please feel free to re-open issues we've closed if there's something we've missed and they still need to be addressed.
All submissions, including submissions by project members, require review. We use GitHub pull requests for this purpose. Consult GitHub Help for more information on using pull requests.
Note that we request issues to be filed for all pull requests. To start, open an issue describing the problem you're looking to solve (or locate an existing issue that represents the problem). Include your approach to solving the problem as this makes it easier to have a conversation about the best general approach.
Please include tests in your pull request.
We recommend making your pull request from a fork. See Creating a pull request from a fork for more information.
