Joomla! Documentation™

A Joomla! CMS installation consists of several Applications:

• Site, also known as the Frontend.
• Administrator, also known as the Backend. It is here that you can make major customisations for your site or Frontend. You can set up how your template looks or you can add new extensions such as components, languages, modules, plugins and templates from the Joomla! Extensions Directory (JED).
• Installer is an application that helps you to install and configure Joomla on your website. Follow the next steps at Installer. This application should be deleted as soon as installation is completed.
