The Developer Guide is a new documentation resource intended for all CiviCRM developers. Using this guide, new developers will learn the basics of creating extensions and leveraging the API -- whereas seasoned developers will find reliable and consistent reference information when needed. To build the guide, this working group is primarily focusing on migrating content from the wiki, while also including other relevant content from blog posts and writing new content to fill in the gaps, as needed.
Detailed information is on this page about the migration process, including how you can help!
Work on this project began in late December, 2016.
