Unlike some years back when websites were almost exclusively static, the standard these days is to have a feature-rich, dynamic web site. Not everybody can build this kind of web site completely from scratch though, hence the handiest solution to have a dynamic website is to use a script application. Many website hosting service providers offer script installers which can be used to add such an app for any of your domain or subdomains, so you will not need to set up anything manually. The key advantage of using an installer tool is the fact that the scripts are available to use in a couple of minutes and the copy that'll be set up is already with the settings necessary for it to run adequately on the specific hosting web server, so you will not have to alter any script or account settings. That way you can easily create one with just a few mouse clicks even though you may have never had a site before.
