Library doesn't have sufficient module documentation

[maxdeviant]

Is your change request related to a problem? Please describe.
As described in the documentation section of the Library Guidelines, Contributors libraries are expected to have mostly complete module documentation, preferably uploaded to Pursuit.

This library currently doesn't have sufficient module documentation -- many publicly-exported types and functions don't have any documentation comments.

Describe the solution you'd like
The library needs to have documentation comments on the majority (and preferably all) public types and functions. Once updated, we should tag a release and upload new module documentation to Pursuit so that folks can use it.
