Unlike some years back when websites were almost exclusively static, the standard these days is to have a feature-rich, dynamic website. Not many people can create this kind of site from scratch though, hence the handiest solution to have a dynamic site is to use a script application. A lot of website hosting providers offer script installers that you can use to add this sort of an app for each of your domain or subdomains, so you'll not have to add anything manually. The key advantage of using an installer tool is the fact that the scripts are available to use in just a few minutes and the copy that'll be installed is already with the settings necessary for it to run efficiently on the specific hosting server, so you will not need to alter any script or account settings. In this way you can effortlessly create one with just a few clicks even when you have never had a site before.
