Expected Behaviour:

All exported types in the API docs should have a typedoc comment explaining what they're for. Bonus points for generic types and parameters too!

Actual Behaviour:

A lot of the constructs in the API docs have very little description of what they do. We should beef up our typedoc comments to address this for all publicly exported types.
