Unlike some years ago when web sites were almost exclusively static, the standard these days is to have a feature-rich, dynamic Internet site. Not many people can build this kind of website completely from scratch though, hence the most convenient solution to have a dynamic website is to use a script app. Many web hosting providers offer script installers you can use to add this kind of an application for each of your domain or subdomains, so you'll not need to set up anything manually. The best thing about using an installer tool would be that the scripts are ready to use in just a few minutes and the copy that will be installed is already with the settings required for it to run efficiently on the particular hosting web server, so you'll not have to modify any script or account settings. This way you can quickly create one with only a few clicks even though you may have never had a website before.
