I'm going to need to start putting together some end-user documentation for my software I'm working on. I'm looking for a good HTML/Browser-based help file solution. I am NOT looking for the CHM solution. I'm looking for just a good hierarchical/structured HTML help documentation system that is viewable in the browser.
Also, if its searchable, that is a big plus. Any good recommendations besides just rolling my own?
UPDATE
I was hoping for a solution that ran locally on a users computer.
