It's easy to get started creating your website. Knowing some of the basics will help.
What is a Content Management System?
A content management system is software that allows you to create and manage webpages easily by separating the creation of your content from the mechanics required to present it on the web.
In this site, the content is stored in a database. The look and feel are created by a template. Joomla! brings together the template and your content to create web pages.
Site and Administrator
Your site actually has two separate sites. The site (also called the front end) is what visitors to your site will see. The administrator (also called the back end) is only used by people managing your site. You can access the administrator by clicking the "Site Administrator" link on the "User Menu" menu (visible once you login) or by adding /administrator to the end of your domain name. The same user name and password are used for both sites.
