You don’t need any special help format. Pure HTML files is fine in itself. People know how to use a browser, and writing pure HTML is pretty easy. Just type up the text in a word processor and markup the appropriate paragraphs, headings, and so on.
If you’re okay with PDF help files, you could use a DTP to make one. Something like Scribus is useful.
Have a look at the range of CHM creators in Google. CHM’s can also be used for e-books. I did a search for CHM creator and got dozens of listings.
I like HTML but I also use PDF files.
You can write your help files in just about any word processor and embed pictures etc. Once that’s done than export or print them to PDF. There’s alot of program out there that snap right in to do that for you. They won’t break the bank.
OK so now you have PDF files. You can code the F1 key to bring up your help file whenever its pressed.

You can also go here:
It will also do screen captures and it’s free.
Get a microphone and do screen captures instead of help files.
My support calls dropped by 90% when I did this as opposed to help files and manuals. More imp when a end-user has a prob they can be referred to the correct movie and SEE what needs to be done.
I can do a entire movie on a subject faster than messing with help files.
