What are help screens?
Throughout the Administrator Back-end there are help screens available to guide you in your use of Joomla! You access these screens by clicking on the Help button on the toolbar. Each screen in the Administrator calls a different help screen so the information you are presented with is relevant to what you are looking at in Joomla! In addition, the Help -> Joomla! Help menu option presents you with an alphabetical list of all the help screens. Some installed components might also include their help screens on this list.
By default, help screens are pulled from a remote server at help.joomla.org and displayed in a popup window. However, there is a setting in Global Configuration which allows you to change the location of the remote help server, or to pull help screens from a directory local to your website.
