Unlike some years back when sites were almost exclusively static, the standard these days is to have a feature-rich, dynamic web site. Not many people can create such a site from scratch though, hence the most convenient solution to have a dynamic website is to use a script application. Lots of website hosting companies offer script installers that can be used to add this kind of an application for any of your domain name or subdomains, so you will not need to set up anything manually. The best thing about using an installer tool is the fact that the scripts are ready to use within a few minutes and the copy which will be installed is already with the settings necessary for it to run correctly on the specific hosting server, so you'll not need to modify any script or account settings. This way you can easily create one with just a few clicks even if you have never had a website before.
