In Joomla! 2.5 Essential Training, Jen Kramer uses Joomla! to build a web site from scratch—no programming required—and guides site designers through the process, from installation to launch. The course demonstrates how to create and organize content; add menus, sidebars, and other features; change the look with templates; install plug-ins and extensions; assign specific users to create and edit content; and much more. Jen also shows how to evaluate the quality of third-party extensions and templates and how to download and install them, and emphasizes the importance of backups for your Joomla! site, with details on creating and storing those backups.
