Joomla is a web application that makes it easy for groups of people to build a website.

In fact Joomla is so easy to use that it is a good tool for even a single individual to use when building a web site.

Applications like Joomla are called "Content Management Systems" (CMS). You can read more about CMS at Wikipedia .

Two of the other more popular CMS applications are Plone and Drupal . Joomla is probably the easiest to use and best supported of the more popular CMS applications.
