Unlike some years ago when sites were almost exclusively static, the standard currently is to have a feature-rich, dynamic website. Not many people can create such a website from scratch though, therefore the most convenient 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 type of an app for each of your domain name or subdomains, so you'll not need to install anything manually. The key advantage of using an installer tool is that the scripts are available to use in a couple of minutes and the copy that will be installed is already with the settings needed for it to run properly on the particular hosting server, so you'll not have to modify any script or account settings. In this way you can effortlessly create one with just a couple of clicks even when you have never had an Internet site before.
