We'd love to have your patches and contributions!
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.
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.
After a pull request is approved, we merge it. Note our merging process differs from GitHub in that we pull and submit the change into an internal version control system. This system automatically pushes a git commit to the GitHub repository (with credit to the original author) and closes the pull request.
Please include unit tests when contributing new features, as they help to a) prove that your code works correctly, and b) guard against future breaking changes to lower the maintenance cost. It's also helpful to check that any changes you propose do not break existing unit tests. You can run tests using the command:
