That is correct. The beauty of this framework is that it allows you to create the included files and you can see them with full markup and not have to worry about the folder hierarchy and paths... as the framework builder will update all the paths to be correct.
Before, with a typical PHP include there were not only far more limitation but the paths had to be edited for where the include would be called - not where the actual include file resided - so you really couldn't see your work.
But now, you can save includes right in the includes folder - for example - and you can leave all the header and body information and design your include file like a webpage. Then you just use Framework builder to include it wherever you want.
