Getting Started with JoomlaSimple Handbook
The JoomlaSimple Handbook is a collection of Joomla tutorials aimed at administrators and developers. The administrator tutorials are geared towards less technical Website administrators with limited to no HTML skills (if you learn very basic HTML, your life will be much, much easier). 

Getting Started with Joomla
New to Joomla and don't know where to begin? Soon we will be launching a Newbies section, so check back soon. 

Public Disclaimer
A product of the Soapbox Collective, this manual does not apply to every Joomla set-up. This Handbook will only be useful to you, the administrator, if

• You are administering Joomla version 1.0.8 - 1.0.15. or
  NOW ALSO - Joomla 1.5
• You are using the JCE WYSIWYG Text Editor with File Manager Plugin. If you're not, many of the step-by-step instructions won't match your Joomla interface, and you will be confused.

 The following images show how items, menus, and articles can be modified by a non-technical Joomla administrator in Joomla 1.0. and 1.5. You will see these buttons and controls across Joomla.
