Add a "Discussions" section to the repo for non-bug-report questions

[jordan-bravo]

Is your feature request related to a problem? Please describe.

I have a question about usage but it is not a bug report nor a feature request, and so it probably does not belong as an issue.

Describe the solution you'd like

It might be a good idea to add a "Discussions" section to the repo for Q&A, usage discussions, etc.

Describe alternatives you've considered

The alternative is to create an issue when questions arise.

Additional context

For lack of anywhere else to ask, I created issue #88 with a question on usage.
