Hi @hfhoffman1144 , I've applied a few changes directly to your PR, they're just general-level, but LMK if you want to reverse anything.

I have one request about adding a quick usage example.

Also, there may or may not be some changes to the code here after addressing my comments in the tutorial PR.

A classic descriptive commit that resolves a unclear situation 🤣

Thanks for applying the updates here as well :)
