A module map is a visual layout of module positions for any given template. Below is the module map for the Protostar template, the default template that comes with your Joomla 3.0 site. Module maps are extremely important to have as you develop a site. In fact, we believe that they are so important, if you are considering a template that doesn't feature a module map, we recommend that steer clear of it. Consult with this module map as you create and position content for your Joomla site.
