Hi there,
I'd be interested in contributing some notebooks (eventually). However, CONTRIBUTING.md currently does not contain a description how to do it on a technical as well as process level (I guess how PRs are managed here?).
A link to Katharine Hyatt's description might be sufficient. However, I'm assuming that you want to adapt it to this repo, specifically, since you probably want to have very novice contributors in mind as well.
Also: keep up the good work in general :-)
