Unlike some years ago when Internet sites were almost exclusively static, the standard currently is to have a feature-rich, dynamic Internet site. Few people can create such a website completely from scratch though, therefore the handiest solution to have a dynamic site is to use a script app. A lot of web hosting providers offer script installers which you can use to add this type of an app for any of your domain or subdomains, so you will not need to install anything manually. The main benefit of using an installer tool would be that the scripts are ready to use within a few minutes and the copy that'll be set up is already with the settings required for it to run properly on the particular hosting web server, so you will not need to modify any script or account settings. In this way you can quickly create one with simply a few clicks even though you may have never had a site before.
