Ever wondered how Joomla sections and categories and the frontpage all fit together?  Or maybe how the menus modules are arranged, or how to get around the 2-category limit?  I see these questions a lot so I've put together a PDF of diagrams to help explain how all these things work in Joomla.  This PDF is a must for everyone putting together a web site with Joomla.

Download Version 1.0 of the PDF: understanding_the_structure_of_joomla.pdf

Here is a sample diagram from the PDF:

Understanding how Joomla sections and categories work with the menu

For more screenshots from the PDF, see the permanent Joomla Structure PDF reference page.

If you have any other ideas for what others areas of Joomla structure could do with a diagram, by all means leave a comment.
