Put the information where people need it
Embedding assistance in the interface works better than sending people to other pages for the information they need.
Just as software should explain itself, your site's interface should offer advice, rather than requiring people to leave the page, go wandering around, find something relevant, and write it on a yellow sticky (or memorize it) and then return and try again.
Sure, you may need to provide a big pile of information on other pages, in the form of FAQs and Help. But start out by giving people a word to the wise, right when they need it.
When asked how useful they considered conventional help systems attached to software, almost three quarters of novice users call it "not helpful." (Two thirds of experts say the same thing).
The whole idea of a separate help facility supporting users is antiquated, an echo of paper manuals.
Yes, you may need to provide full documentation in a separate place, but you should let guests avoid that big pile, by offering them on-the-spot tips.
