Install your Joomla application

This article assumes you've downloaded the open source PHP application you want to use on your web site.  After you've downloaded and unzipped the application to a folder on your server, you can FTP it up to the server.

For information on creating an FTP account: http://track.gizmobeach.com/KB/a9/how-do-i-create-an-ftp-account.aspx

Make sure when you FTP the application to the server, that you upload it to your /wwwroot folder.  This is the folder for your web site.  Any of the other folders you see when you first FTP in, are NOT part of your web site and your application will NOT work there.

After you've FTP'd your application to your web site, simply open a browser and go to your web site.

The Joomla install wizard will appear and should step through it and follow the directions to install the application.  At the end of the wizard, your application will be installed and ready to use.

The final step will require you to delete the installation folder from the web site in order to continue.  This is a security measure they've added to prevent others from re-installing Joomla for themselves or some other nefarious reasons.

Once you've done that, you will see your fully installed and ready-to-go application.
