What is Joomla?
It is an award-winning content management system (CMS), which enables you to build Web sites and powerful online applications.
What’s a content management system?
A content management system is software that keeps track of every piece of content on your Web site, much like your local public library keeps track of books and stores them. Content can be simple text, photos, music, video, documents, or just about anything you can think of. A major advantage of using a CMS is that it requires almost no technical skill or knowledge to manage.
