Where to Start

Joomla! 1.5 and later is documented on the wiki at docs.joomla.org.

A good place to start is on the Developers page which links you to pages about participation and other resources.

The Development Category on the Documentation Wiki provides a list of all the development related pages.  We recommend you bookmark this link where you can find it easily.

The following Wiki categories are also of interest to developers:

• Framework
• Security

Collected information about extensions can be found on the following wiki category pages:

• Plugins

API

The Joomla! 1.5 codebase has been analysed by an automated tool that looks at specially formatted comments embedded in the source code itself.  The output for the current stable release of the Joomla! 1.5 Framework can be found at api.joomla.org and the current SVN can be found at api.joomla.org/svn.

Licensing

Information on Joomla!'s license, how to license Joomla! extensions, and other licensing issues can be found on the Open Source Matters licensing page.

Legacy Information

Some developer documentation for the legacy 1.0.x series can still be found on help.joomla.org.  Please note that this information is no longer being maintained.

The old Developer Wiki is still available but the accuracy and currency of the information cannot be guaranteed.  Most information has already been moved to the new Docs wiki (see links above).  If you find a page of information on the old wiki site that you think has value, please help us out by adding it to the new Docs wiki.
