We'd love to accept your patches and contributions to this project. There are just a few small guidelines you need to follow.
This project is released with a Contributor Code of Conduct. By participating in this project you agree to abide by its terms.
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. When you submit pull requests, a helpful Google CLA bot will tell you if you need to sign the CLA.
Before you make significant code changes, please open an issue to discuss your plans. This will minimize the amount of review required for pull requests.
All submissions require review. We use GitHub pull requests for this purpose. Consult GitHub Help for more information on using pull requests.
