Joomla! is an award-winning content management system (CMS), which enables us to build Web sites and powerful online applications. Many aspects, including its ease-of-use and extensibility, have made Joomla the most popular free Web site software available. Joomla! is an open source solution that is available to everyone.
A major advantage of using a CMS is that it requires almost no technical skill or knowledge to manage it. With a minimal amount of instructions, clients can be empowered to easily manage their own sites themselves.
If a client need specialized functionality, Joomla! is highly extendible and thousands of extensions (most for free under the GPL license). You can see many of them on the the Joomla Extensions Directory.
Joomla! functionality is simple and easy to use, making editing your own content fast and manageable for anyone within your company. All you need to make your site work effectively is what you want your website to say and do, and Joomla! CMS takes care of the rest.
