Unlike some years ago when Internet sites were almost exclusively static, the standard currently is to have a feature-rich, dynamic website. Not many people can build this type of website from scratch though, hence the handiest solution to have a dynamic site is to use a script application. Lots of hosting service providers offer script installers that can be used to add this sort of an application for each of your domain name or subdomains, so you will not have to set up anything manually. The 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 necessary for it to run the way it should on the specific hosting web server, so you will not have to adjust any script or account settings. That way you can quickly build one with only a couple of clicks even when you have never had a website before.
