There are several ways to install Joomla!.
If you want to test Joomla! and you haven't purchased a domain yet, you can install Joomla! on your own computer (without your site appearing on the Internet), you can install it using the XAMPP package. You can also create a working website at demo.joomla.org, which is easy and well-supported.
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.
- Option One: One Click Installs. Many hosting companies offer "instant" installation of Joomla!. Follow the instructions your host provides for a one click install.
- Option Two: Conventional Installs. This method requires that you copy the Joomla! zip file to your hosting account, unzip, create a database, and then run the installation. Complete instructions can be found in Installation for Joomla 2.5 and Installation for Joomla 3.x and further information at Joomla! Installation Resources. This video takes you through the steps.
- Option Three: Demo Site. If you used the Demo Site, you can follow the instructions provided to back up and move the site to your existing host or establish a hosting account at the end of the free 30 day trial. (Note that the Joomla! Project receives a royalty if you choose paid hosting from that site.)
For support with installation, you can ask questions in the installation forum.
