1Want to contribute? Great! First, read this page (including the small print at 2the end). 3 4### Before you contribute 5Before we can use your code, you must sign the 6[Google Individual Contributor License Agreement] 7(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### Disclosure 21If your tests uncover security vulnerabilities, please first report directly to 22the maintainers of the libraries. You should only submit tests to us once the 23bugs have been acknowledged or fixed. 24 25Google has several 26[security reward programs](https://www.google.com/about/appsecurity/programs-home/) 27that provide cash rewards for quality security research that identifies or fixes 28security vulnerabilities in products that we provide or proactive security 29improvements to select open-source products. If your tests found or helped fix 30vulnerabilities that are in scope you should submit them to these programs. 31 32If you have any question with regard to disclosure, please email us at 33security@google.com. 34 35### Code reviews 36All submissions, including submissions by project members, require review. We 37use GitHub pull requests for this purpose. 38 39### The small print 40Contributions made by corporations are covered by a different agreement than 41the one above, the 42[Software Grant and Corporate Contributor License Agreement] 43(https://cla.developers.google.com/about/google-corporate).
