This module integrates into the Help module (using the hook_help() hook) to add help messages based on the URL and/or by user role. There is an administration form that allows users to set the messages and where they appear on the site. Multiple help messages can be added to the same page at once, the administration form can be ordered to sort the order that these messages appear.

In order to make the help messages appear you need to make sure that the $messages variable is printed on your template layer. Most themes will do this.
