@wtbarnes, would you consider a short review about it reads from someone outside the project?

[wtbarnes]

Sorry, was late weighing in. I think the added info on the landing page and especially the tutorial notebook help to give a lot of context as to how to use this. Thanks for adding that!

[byrdie]

No, I'm sorry for not giving you more time to review. Let me know if you notice anything and I'll fix it with a quick PR.

[wtbarnes]

No worries and will do!
