Due to the nature of the keywords, I find it difficult to easily google this. I want to implement a "help" item on the menu bar that will launch some basic documentation for the user to read, after I have written it. Are there any standards or libraries I should be aware about before diving into this aspect? The program incorporating the "help" functionality will be a C# WPF Desktop application.
Example from MS Word :
I'm sure they don't reinvent the wheel every time they use the help function, and I don't want to either. Where can I look to find something open source that is similar to this functionality and maybe some general guidelines on how to write help for non-technical and technical users?
