Unlike some years ago when websites were almost exclusively static, the standard today is to have a feature-rich, dynamic site. Few people can create this type of site completely from scratch though, therefore the simplest solution to have a dynamic site is to use a script app. A lot of website hosting providers offer script installers that can be used to add this sort of an app for any of your domain name or subdomains, so you'll not need to add anything manually. The best thing about using an installer tool is that the scripts are ready to use in just a few minutes and the copy that'll be installed is already with the settings required for it to run efficiently on the specific hosting web server, so you will not have to change any script or account settings. In this way you can effortlessly create one with simply a few clicks even if you have never had a website before.
