Follow the Examples project on Twitter: The Examples for Developers project has a Gittip team page. You can contribute financially to the project: Code Examples For Drupal The Examples for Developers project aims to provide high-quality, well-documented API examples for a broad range of Drupal core functionality.
The Examples project contains many modules which hopefully illustrate best practices for implementing various Drupal APIs. Developers can learn how to use a particular API quickly by experimenting with the examples, and adapt them for their own use. Note also that these modules demonstrate internals for Drupal development in PHP (and some JavaScript). How To Use These Modules As Modules You can enable these modules just like any others. API.Drupal.Org You can also browse the documentation generated from this project on api.drupal.org. Browse The Repo Adapt The Code Core Only How can you help? I'm glad you asked: Theme developer.
