An index of documentation pages about add-ons, previously known as contributed plugins or contributed code.

An add-on is code contributed to Moodle which is not included in the standard Moodle download package.

Moodle = core code + plugins. Plugins may be either standard plugins (included in the Moodle download package) or add-ons.

Add-on code is usually managed by the developer of the plugin or patch; however, as people change jobs or move on for whatever reason others can volunteer to step in to serve as the primary maintainer of a contribution.

The code is hosted on a the version control system (VCS) of the developers choice. There are various Git repositories; however, the most commonly used Git repository is Github.com.

Add-on developers can create their own publicly accessible Git repository of the code (for an example see https://github.com/moodlehq/). Plugins typically use the following naming convention: moodle-{type}_{name} so that the book activity module would be named moodle-mod_book. Developers are encouraged to be consistent.

Add-ons may be browsed and downloaded from the Moodle plugins directory.

Anthony Borrow, the CONTRIB Coordinator, is happy to answer any questions related to add-on code and will help direct folks to the appropriate developer. Feel free to contact Anthony via Moodle message.
