Unlike some years ago when websites were almost exclusively static, the standard these days is to have a feature-rich, dynamic Internet site. Not everybody can create this kind of website from scratch though, so the handiest solution to have a dynamic site is to use a script app. A lot of web hosting providers offer script installers which can be used to add this kind of an application for any of your domain or subdomains, so you will not have to install anything manually. The best thing about using an installer tool would be that the scripts are ready to use in a few minutes and the copy that will be set up is already with the settings necessary for it to run properly on the particular hosting server, so you'll not have to change any script or account settings. That way you can effortlessly build one with simply a couple of clicks even if you have never had a website before.
