What documentation is included in the box with the iPad 3? The Apple website states that there is "Documentation" included in the box and several unboxing videos on YouTube clearly show some kind of physical documentation - but don't state what it is. What should this documentation include?

Specifically, I am wondering if there should be some kind of newbie-getting-started-guide included? And what this contains?
I just checked the box for my iPad 2. There is essentially nothing other than:


a tiny card with minimal instructions. This tells you that there is further documentation at help.apple.com/ipad, along with information about needing to download iTunes, etc.
The obligatory "Important Product Information Guide" containing a whole lot of legal stuff. 
Some Apple stickers. 


So I think your best bet for information would be the iPad user manual linked in the other answer.

A couple of photos of the card are shown below:



Please note that this is from the iPad 2 so this may have changed since I bought mine. Although Apple has been moving towards less and less documentation over the years.
