Unlike some years ago when sites were almost exclusively static, the standard today is to have a feature-rich, dynamic website. Few people can build this type of site from scratch though, hence the most convenient solution to have a dynamic site is to use a script app. Many hosting companies offer script installers you can use to add this sort of an app for any of your domain name or subdomains, so you will not need to set up anything manually. The benefit of using an installer tool is that the scripts are ready to use in just a few minutes and the copy that will be set up is already with the settings required for it to run correctly on the particular hosting web server, so you will not have to change any script or account settings. That way you can effortlessly create one with simply a few mouse clicks even if you have never had a site before.
