| # How to Contribute | 
 |  | 
 | We'd love to accept your patches and contributions to this project. There are | 
 | just a few small guidelines you need to follow. | 
 |  | 
 | ## Contributor License Agreement | 
 |  | 
 | 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. | 
 |  | 
 | ## Code reviews | 
 |  | 
 | All submissions, including submissions by project members, require review. We | 
 | use GitHub pull requests for this purpose. Consult | 
 | [GitHub Help](https://help.github.com/articles/about-pull-requests/) for more | 
 | information on using pull requests. | 
 |  | 
 | ## Community Guidelines | 
 |  | 
 | This project follows [Google's Open Source Community | 
 | Guidelines](https://opensource.google/conduct/). |
