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.
Before you start working on a larger contribution, you should get in touch with us first. Use the issue tracker to explain your idea so we can help and possibly guide you.
All submissions, including submissions by project members, require review. Please follow the instructions in the contributors documentation.
Setting up IntelliJ to work on the plugin can be tricky. Please read this guide for instructions.
Contributions made by corporations are covered by a different agreement than the one above, the Software Grant and Corporate Contributor License Agreement.
