Material Motion Exploring solutions that will empower creators with the tools needed to describe and implement rich, interactive motion on any platform. Edit this page · History

Accepting contributions

We use the following rules for accepting contributions.

  1. We require that all contributors sign Google’s Contributor License Agreement.

  2. All contributions must be approved by a member of the core contributors team.

Before we can use your code, you must sign the Google Individual Contributor License Agreement (CLA), which you can do online. The CLA 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.

Contributions made by corporations are covered by a different agreement than the one above, the Software Grant and Corporate Contributor License Agreement.
