Joomla is a free and open source content management system (CMS) for publishing content on the Web and intranets. It comprises a model–view–controller (MVC) Web application framework that can also be used independently.
Joomla is written in Object-oriented PHP, and uses software design patterns, stores data in a MySQL, and includes features such as page caching, RSS feeds, printable versions of pages, news flashes, blogs, polls, search, and support for language internationalisation (i18n).
Within its first year of release, Joomla was downloaded 2.5 million times. Over 6,000 free and commercial plug-ins are available.

Installation
I found installation to be very straight forward, simply unpack the downloadable zip into a web-accessible location on the server making sure that it is writeable by the web-server, then navigate to that location to go through the install procedure. It allows the use of a table prefix so that it can be installed into existing MySQL databases along with other applications such as Wordpress or MediaWiki.
A useful feature of the Joomla installation is that it allows the newly set up site to be optionally populated with sample data to help Joomla-noobs get started.
Skinning
todo... (removed old links, need new ones)
Extensions
See extensions.joomla.org for a comprehensive extension search tool. They have thousands of useful extension that are very well organised and reviewed, many of them with live demos.
Some extensions to look in to
- ProjectFork - project management and time-tracking system
Documentation
One problem with Joomla is that the documentation is very good for users, but very sparse for developers. Most of the API documentation is empty and still waiting to be populated by developer contributions. I found that for writing my first extensions I needed to wade through the Joomla code to figure out how to do things.
- Joomla documentation wiki - a MediaWiki (not a particularly good sign in my opinion :-/)
- Joomla API docs
Technical issues
I made my first Joomla extension on August 2015 for the Ligmincha Brasil site. It allows single sign-on between the Joomla and the volunteers MediaWiki. Any users of the wiki who are in the specified MediaWiki group ("Joomla" by default) are automatically able to access the administration side of the Joomla if they are logged in to the wiki.
I had some trouble at first because one of the plugin events I wanted to use, onAfterInitialise, was not being called, but the other, onUserAthenticate, was. It turned out (after I asked a question on stackoverflow) that the events are only triggered for plugins in their corresponding group, so if you want a plugin that uses events in different groups, you need to make your extension into a package of multiple plugins.
It turned out after I got the onAfterInitialise event to trigger in my code (by making it a system plugin) that I didn't even need to use the onUserAthenticate event at all because I could call JFactory::getSession()->set directly which means that user authentication isn't required. The code is in our Git repo here.
