Abstract:

Regardless of what sort of Content Management System or Web application framework you might use to develop your Web site, there are some basics you should cover. A sophisticated user interface and rich content is great to have, but before you get to that, you should provide the basic files that users anticipate finding and that tell both humans and machines what your site does.
