docs: direct users to library API

[bashbunni]

In an attempt to improve our documentation while keeping the cost of maintenance as low as possible, I think it would be valuable to direct users on how to use the examples provided. A lot of people who are new to Go aren't aware that they can see the godoc of our packages online.

Lmk your thoughts, I think this disclosure makes it easier for users to learn to find what they're looking for.
