Unlike some years back when websites were almost exclusively static, the standard today is to have a feature-rich, dynamic site. Few people can create this kind of site completely from scratch though, hence the simplest solution to have a dynamic website is to use a script application. Many website hosting providers offer script installers you can use to add this sort of an app for each of your domain or subdomains, so you will not need to set up anything manually. The best thing about using an installer tool would be that the scripts are ready to use within a few minutes and the copy which will be set up is already with the settings needed for it to run efficiently on the particular hosting web server, so you will not have to change any script or account settings. This way you can easily create one with simply a couple of mouse clicks even if you have never had a site before.
