+## We Need Your Help!
+
+We need your help making the guides even better. In particular, here are the easiest ways to contribute:
+
+1. **Update Guides.** Review existing guides and update outdated content, add troubleshooting tips or add/update images
+2. **Fill Out Guides.** Find guides that are [simply stubs](https://github.com/codepath/android_guides/issues/2) and fill them out with content.
+3. **Create New Guides.** Review the [missing topics list](https://github.com/codepath/android_guides/issues/2) and create new topic guides.
+
+We [maintain a master missing topics list](https://github.com/codepath/android_guides/issues/2) that contains the most important missing topics. Also look for items in the cliffnotes with the **Needs Attention** mark which indicates the guide needs some love. If you see a topic you'd like added, please check the [issues](https://github.com/codepath/android_guides/issues) for this repository to let us know.
