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