Hi Ahoo! Since user guide should be exposed to the user "on-line" , I think it can be in html format.
The design considerations MUST be an ascii file (es. txt) because it can be opened with an editor like VI.
Absolutely you can't use the .doc format (MS
Word) !! You can't assume they will read your documentation on WIN platform and they'll have the MS Word installed on their machine!
Hope it helps...
