Joomla is a content management system (CMS) that enables you to create a website or online shop from scratch, or to improve an existing website. As with all software, there are certain requirements that must be met in order to run Joomla.
To use Joomla, your computer must have a web browser that is compatible with the Joomla content management system and the Joomla extension API. Additionally, your computer must have a valid SSL certificate, and your web server must be able to host a PHP application.
The Joomla software is free to download and use, but there are certain features that require payment. Joomla also has a support system that can be accessed by email or telephone.
