Unlike some years back when websites were almost exclusively static, the standard nowadays is to have a feature-rich, dynamic Internet site. Not many people can create this type of site from scratch though, hence the handiest solution to have a dynamic website is to use a script application. A lot of web hosting companies offer script installers you can use to add this kind of an app for any of your domain or subdomains, so you'll not need to set up anything manually. The benefit of using an installer tool would be that the scripts are available to use within a few minutes and the copy which will be set up is already with the settings required for it to run the way it should on the particular hosting web server, so you'll not have to adjust any script or account settings. In this way you can quickly create one with only a few clicks even when you have never had a website before.
