Unlike some years ago when sites were almost exclusively static, the standard today is to have a feature-rich, dynamic web site. Not many people can build this kind of web site from scratch though, therefore the handiest solution to have a dynamic website is to use a script application. Many website hosting companies offer script installers you can use to add this sort of an application for each of your domain name or subdomains, so you will not have to add anything manually. The main benefit of using an installer tool is that the scripts are available to use in just a couple of minutes and the copy which will be set up is already with the settings needed for it to run correctly on the specific hosting server, so you'll not have to adjust any script or account settings. In this way you can quickly create one with only a couple of clicks even though you may have never had an Internet site before.
