Before you can begin using Joomla! you will need a working installation of Joomla! If you want your site to be available on the Internet, make sure that you have an account on a web server. For most people this means signing up with a hosting company and purchasing a domain that will serve as your site's main address.
- If you want to test Joomla! and you haven't purchased a domain yet, you can see and experiment with a working installation at demo.joomla.org. As an added bonus, the demo site provides links for creating a working Joomla! website with a 30 day trial. (Note that the Joomla! Project receives a royalty if you choose paid hosting from that site.)
- Already have a hosting company? Joomla! is offered by most hosting companies as a "One Click Installs" for their customers. The "One Click Install" offers an "instant" installation of Joomla! which is quick and easy. Follow the instructions your host provides.
- Use the conventional method of installation. This requires you to copy the Joomla! zip file to your hosting account, unzip, create a database, and then run the installation. Complete instructions can be found at Installing Joomla. Further information can be found at Joomla! Installation Resources.
- Install Joomla! on your own computer (without your site appearing on the Internet), you can install it using the XAMPP package. Install XAMPP and then use the "conventional method" to get your Joomla! test site working.
For support with installation, you can ask questions in the installation forum.
