iPhone app, help pages, multiple pages, quick to develop?

I need to provide some help for my app. I'm going to have some info buttons on some screens.

Initially I'd like them to be directed to the exact help page, but I'd like them then to be able to navigate to other pages in the help system.

What should I use, I'm looking for something quick to develop and quick to modify.

I'm thinking local html pages perhaps ?

Any examples / advice

I think the best way to do this is using a UIWebView to load HTML pages from your server. This way the user doesn't leave you app and the information can be updated or change as you may need.
