+# How to become a contributor and submit your own code
+
+## Contributor License Agreements
+
+We'd love to accept your sample apps and patches! Before we can take them, we
+have to jump a couple of legal hurdles.
+
+Please fill out either the individual or corporate Contributor License Agreement (CLA).
+
+  * 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]
+    (https://cla.developers.google.com).
+  * If you work for a company that wants to allow you to contribute your work,
+    then you'll need to sign a [corporate CLA]
+    (https://cla.developers.google.com).
+
+Follow either of the two links above to access the appropriate CLA and
+instructions for how to sign and return it. Once we receive it, we'll be able to
+accept your pull requests.
+
+## Contributing A Patch
+
+1. Submit an issue describing your proposed change to the repo in question.
+2. The repo owner will respond to your issue promptly.
+3. If your proposed change is accepted, and you haven't already done so, sign a
+   Contributor License Agreement (see details above).
+4. Fork the desired repo, develop and test your code changes.
+5. Ensure that your code adheres to the existing style in the sample to which
+   you are contributing. Refer to the
+   [Android Code Style Guide]
+   (https://source.android.com/source/code-style.html) for the
+   recommended coding standards for this organization.
+6. Ensure that your code has an appropriate set of unit tests which all pass.
+7. Submit a pull request.
