| 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://developers.google.com/open-source/cla/individual?csw=1) |
| (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. |
| |
| ### Code reviews and other contributions. |
| |
| **All submissions, including submissions by project members, require review.** |
| Please follow the instructions in [the patching guide](/patching.md). |
| |
| ### The small print |
| |
| Contributions made by corporations are covered by a different agreement than the |
| one above, the [Software Grant and Corporate Contributor License |
| Agreement](https://cla.developers.google.com/about/google-corporate). |
