1Want to contribute? Great! First, read this page (including the small print 2at the end). 3 4### Before you contribute 5Before we can use your code, you must sign the 6[Google Individual Contributor License 7Agreement](https://cla.developers.google.com/about/google-individual) 8(CLA), which you can do online. The CLA is necessary mainly because you own the 9copyright to your changes, even after your contribution becomes part of our 10codebase, so we need your permission to use and distribute your code. We also 11need to be sure of various other things—for instance that you'll tell us if you 12know that your code infringes on other people's patents. You don't have to sign 13the CLA until after you've submitted your code for review and a member has 14approved it, but you must do it before we can put your code into our codebase. 15Before you start working on a larger contribution, you should get in touch with 16us first through the issue tracker with your idea so that we can help out and 17possibly guide you. Coordinating up front makes it much easier to avoid 18frustration later on. 19 20### Code reviews 21All submissions, including submissions by project members, require review. We 22use Github pull requests for this purpose. 23 24### The small print 25Contributions made by corporations are covered by a different agreement than 26the one above, the 27[Software Grant and Corporate Contributor License 28Agreement](https://cla.developers.google.com/about/google-corporate). 29
