I'll list down the usual steps invloved to install a php application. (But I don't know exactly about this software) (1) Make sure you have php and mySQL running on the web hosting service which your .com domain is forwarded. (You may call your web hosting service and verify this) (2) Most of the time you are required to create a blank database and the settings need to be provided in the installation wizard (3) Download the code (Usually it comes as a compressed file) (4) Extract it and upload to the root folder of your server using your FTP account. (Make sure you have index.html or index.php file in the root folder which the domain is forwarded) (5) Open your web browser and go to your site. Usually there should be an installation wizard to guide you through the installation by giving required instructions. This is just a common guideline. However you may give it a try. It must be easy
