If you are interested in developing your own theme for Friendica, or expanding an existing theme. Have a look at this article about themes in Friendica.

There is a git repository for themes and theme customizations created by the Friendica community.

You can easily expand the core functionality of Friendica with addons. In the Friendica addon development article, you'll find information about the addon format and the hooks that Friendica provides so your addon can jump into the workflow at the different places.

To ease setting up an environment for Friendica development, we have created a Vagrant VM that can be used to easily setup a server with some local users to test things. This is ideal for working on themes, local acting addons or other things that only affects the local server. If you want to work on federation issues, you'll likely need more then just this Vagrant VM.
