Online help can be fully integrated into an application or provided as a standalone help volume. Fully integrated help allows a user to directly access help information from an application by using a Help menu or Help key. A standalone volume on the other hand, can only be displayed using the desktop Help Viewer.
A system administrator may choose to add a standalone help volume to the desktop when an application does not provide integrated help or a customized environment provides a supplemental help volume. See "Standalone Help" for instructions to install a standalone volume on the desktop.
