Unlike some years back when web sites were almost exclusively static, the standard these days is to have a feature-rich, dynamic website. Few people can build this sort of website completely from scratch though, therefore the simplest solution to have a dynamic website is to use a script application. A lot of website hosting service providers offer script installers you can use to add this kind of an app for any of your domain name or subdomains, so you'll not need to install anything manually. The best thing about using an installer tool would be that the scripts are ready to use in just a couple of minutes and the copy which will be installed is already with the settings necessary for it to run properly on the specific hosting web server, so you'll not have to alter any script or account settings. In this way you can easily create one with only a few mouse clicks even when you have never had a site before.
