What is an add-on?
An add-on, previously known as a contributed plugin, contributed code, or "contrib" for short, is understood to be all code contributed to Moodle which is not included in the standard Moodle distribution.
Moodle code = core code + plugins. Plugins may be either standard plugins (included in the Moodle distribution) or add-ons.
Where can I download add-ons from?
How do I install an add-on?
See Installing plugins for instructions. Some, but not all, contributors include a "Read me" file with instructions in their plugin package.
In a typical install, you will probably copy some php files into one or more areas of you Moodle site's code, then click on the Site administration link called "Notifications" to start the install process.
How do I apply a patch?
Why doesn't my newly installed add-on show up in the list of plugins?
Firstly, check that you have visited your admin index page http://your_moodle_site.org/admin/index.php to complete the installation. Next, check that you unzipped the archive to the correct folder, and that the new plugin folder is not contained within another folder.

Is there any information on creating a new add-on?
Yes! See dev:Developer documentation. More coming soon!
