Unlike some years ago when websites were almost exclusively static, the standard currently is to have a feature-rich, dynamic web site. Not many people can create this sort of site completely from scratch though, therefore the handiest solution to have a dynamic site is to use a script app. A lot of hosting service providers offer script installers which can be used to add this sort of an application for any of your domain or subdomains, so you will not have to set up anything manually. The main advantage of using an installer tool would be that the scripts are available to use in 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 particular hosting web server, so you will not need to change any script or account settings. That way you can quickly create one with just a few mouse clicks even though you may have never had a website before.
