We'd love to hear about how you would like to contribute to Cobalt! Please read through this document first to understand the process and to make sure you know what to expect.
Before Cobalt can use your code, as an unaffiliated individual, you must sign the Google Individual Contributor License Agreement (CLA). You can complete that process online.
If you represent a company that wishes to have one or more employees contribute to Cobalt on behalf of your company, you need to agree to the Software Grant and Corporate Contributor License Agreement.
The Contributor License Agreement 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, get in touch with us to discuss your idea so that we can help out and possibly guide you. Early coordination makes it much easier to avoid frustration later on.
All submissions, including submissions by project members, require review. We currently use Gerrit Code Review for this purpose. Currently, team-member submissions are reviewed privately, and external submissions go through public reviews.
The following steps explain the submission process:
git push origin HEAD:refs/for/masterto upload the review to Cobalt's Gerrit instance.
git commit --amendto add them to the existing commit. Then return to step 2.
