Unlike some years ago when Internet sites were almost exclusively static, the standard today is to have a feature-rich, dynamic site. Not many people can create this kind of website completely from scratch though, therefore the handiest solution to have a dynamic website is to use a script application. Lots of website hosting providers offer script installers that you can use to add this kind of an app for any of your domain or subdomains, so you'll not need to add anything manually. The benefit of using an installer tool is that the scripts are ready to use in a couple of minutes and the copy that will be set up is already with the settings required for it to run properly on the particular hosting web server, so you will not have to adjust any script or account settings. That way you can quickly create one with just a few clicks even when you have never had an Internet site before.
