Before we can take them, we 6 | have to jump a couple of legal hurdles. 7 | 8 | ### Before you contribute 9 | Before we can use your code, you must sign the 10 | [Google Individual Contributor License Agreement](https://cla.developers.google.com/about/google-individual) 11 | (CLA), which you can do online. The CLA is necessary mainly because you own the 12 | copyright to your changes, even after your contribution becomes part of our 13 | codebase, so we need your permission to use and distribute your code. We also 14 | need to be sure of various other things—for instance that you'll tell us if you 15 | know that your code infringes on other people's patents. You don't have to sign 16 | the CLA until after you've submitted your code for review and a member has 17 | approved it, but you must do it before we can put your code into our codebase. 18 | Before you start working on a larger contribution, you should get in touch with 19 | us first through the issue tracker with your idea so that we can help out and 20 | possibly guide you. Coordinating up front makes it much easier to avoid 21 | frustration later on. 22 | 23 | ### Code reviews 24 | All submissions, including submissions by project members, require review. We 25 | use Github pull requests for this purpose. 26 | 27 | ### The small print 28 | Contributions made by corporations are covered by a different agreement than 29 | the one above, the 30 | [Software Grant and Corporate Contributor License Agreement](https://cla.developers.google.com/about/google-corporate). 31 | -------------------------------------------------------------------------------- /LICENSE: -------------------------------------------------------------------------------- 1 | Apache License 2 | Version 2.0, January 2004 3 | http://www.apache.org/licenses/ 4 | 5 | TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION 6 | 7 | 1.
