Where is a complete user's guide for Passbook?
I'm having a lot of trouble learning how to use Passbook.
For example, I downloaded a few loyalty cards, but now when I open Passbook, I see them but nothing else - there's no way to add addiitonal cards, no help, no menus, no nothing. Additionally, I've been unable to find any DETAILED documentation of how to use this new app. Even the Apple site has just a one-page summary.
Does anyone know where there's a good, detailed user's guide for Passbook?
