i have built a website for one of my clients, and it is rather complicated, so they have asked for me to make a user manual for it, how would i go about this? online/offline wiki? pdf file? or is there a specific program to make help files?? thanks
I'd have a docs page that you could refer users to. For example, getmediacore.com/docs or codex.wordpress.org/Main_Page, I'm guessing you could utilize a wiki-type software for the management of the docs.
