[Heuristic] Help and documentation [Justification (From Nielsen)] Even though it is better if the system can be used without documentation, it may be necessary to provide help and documentation. Any such information should be easy to search, focused on the user's task, list concrete steps to be carried out, and not be too large. [Yes but...] 
Far from apologizing for help we should revel in it.Help and documentation should be electronic and in context. For example, micro help (a question mark icon or What's this link which work on mouseover or a small popup) often assist the user without interruption.
