More about the help module

All user help should be presented using the help module. Some examples of help:

• The name of a module (unused, but there).
• The description found on the admin/system/modules page.
• The module's help text, displayed on the admin/help page and through the module's individual help link.
• The help for a distributed-authorization module (if applicable).
• The description of a post type (if applicable).

The text of the help topics listed on administer >> help are maintained on drupal.org in the Drupal modules section. Additional help is often available in sub pages of that section.
