See, e.g., these notes.

The nice thing about Agda is of course the numeric syntactic sugar, allowing you to write actual numbers at the type level.

There’s also an important (and small) book by Pierce: http://www.amazon.com/Category-Computer-Scientists-Foundations-Computing/dp/0262660717 that sheds like on things.

Good luck!
