If you produce software of any complexity you will be aware of the need to provide your users with well written, professionally presented help and reference materials.

I have over 10 years experience in producing MS Windows .CHM and .HLP help files, and WebHelp and JavaHelp for browser based applications. The help can be fully integrated into software applications, right down to field level 'F1' key 'context sensitive' help.

The level (and cost) of integration is up to you.

The source material can be re-purposed existing paper documentation, suitably adapted for online presentation, or all new material written from new in collaboration with appropriate members of you staff.
