I'll do it anyway!
The tutorial code is written with PHP classes, objects and heredoc syntax , which IMO is not suitable for a beginner audience.
The CMS created in the tutorial apparently lets you edit pages' raw HTML code from a form. For a CMS user that doesn't know HTML that's not too useful, while those that do know HTML might as well edit inclusion text files in a text editor and upload with an FTP program. (A CMS like this might be useful if you know HTML but is away from your own computer, though.)
