Contributions to any Google project must be accompanied by a Contributor License Agreement. This is not a copyright assignment; it simply gives Google permission to use and redistribute your contributions as part of the project.
- If you are an individual writing original source code and you're sure you own the intellectual property, then you'll need to sign an individual CLA. Please include your GitHub username.
- If you work for a company that wants to allow you to contribute your work, then you'll need to sign a corporate CLA.
You generally only need to submit a CLA once, so if you've already submitted one (even if it was for a different project), you probably don't need to do it again.
