-Before we can use your code, you must sign the
-[Google Individual Contributor License
-Agreement](https://cla.developers.google.com/about/google-individual) 
-(CLA), which you can do online. The CLA is necessary mainly because you own the
-copyright to your changes, even after your contribution becomes part of our
-codebase, so we need your permission to use and distribute your code. We also
-need to be sure of various other things—for instance that you'll tell us if you
-know that your code infringes on other people's patents. You don't have to sign
-the CLA until after you've submitted your code for review and a member has
-approved it, but you must do it before we can put your code into our codebase.
-Before you start working on a larger contribution, you should get in touch with
-us first through the issue tracker with your idea so that we can help out and
-possibly guide you. Coordinating up front makes it much easier to avoid
-frustration later on.

-### Code reviews
-All submissions, including submissions by project members, require review.
-We use Github pull requests for this purpose.

-Contributions made by corporations are covered by a different agreement than
