Unlike some years ago when websites were almost exclusively static, the standard currently is to have a feature-rich, dynamic website. Few people can build such a site from scratch though, hence the handiest solution to have a dynamic site is to use a script application. Lots of website hosting providers offer script installers that can be used to add this type of an app for any of your domain or subdomains, so you'll not have to add anything manually. The benefit of using an installer tool would be that the scripts are available to use in a couple of minutes and the copy that will be set up is already with the settings necessary for it to run correctly on the specific hosting web server, so you will not need to adjust any script or account settings. In this way you can quickly create one with only a few clicks even if you have never had an Internet site before.
