Unlike some years ago when websites were almost exclusively static, the standard currently is to have a feature-rich, dynamic site. Not many people can build such a site from scratch though, therefore the handiest solution to have a dynamic website is to use a script application. A lot of web hosting providers offer script installers which can be used to add such an app for each of your domain or subdomains, so you will not have to set up anything manually. The main advantage of using an installer tool is that the scripts are ready to use within a couple of minutes and the copy that'll be set up is already with the settings required for it to run the way it should on the specific hosting server, so you'll not need to alter any script or account settings. This way you can effortlessly create one with just a few mouse clicks even though you may have never had a website before.
