| Want to contribute? Great! First, read this page (including the small print at |
| the end). |

| ### Before you contribute |
| Before we can use your code, you must sign the |
| [Google Individual Contributor License Agreement](https://cla.developers.google.com/about/google-individual) |
| (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 through the issue tracker with your idea so that we can help out and |
| possibly guide you. Coordinating up front makes it much easier to avoid |
| frustration later on. |
| |
| ### Code reviews |
| All submissions, including submissions by project members, require review. |
| |
| ### File headers |
| All files in the project must start with the following header. |
