Unlike some years back when web sites were almost exclusively static, the standard today is to have a feature-rich, dynamic website. Few people can create this sort of web site from scratch though, hence the handiest solution to have a dynamic website is to use a script application. Lots of website hosting providers offer script installers you can use to add this sort of an app for any of your domain or subdomains, so you will not need to add anything manually. The advantage of using an installer tool is that the scripts are available to use within a couple of minutes and the copy that'll be set up is already with the settings necessary for it to run efficiently on the specific hosting web server, so you'll not need to modify any script or account settings. This way you can quickly build one with just a few mouse clicks even though you may have never had an Internet site before.
