@goldfish088 - nice work! The issue also mentioned adding docs for the usage of this Operator? Would you be interested in adding those docs as part of this PR?

[goldfish088]

Hi @jroachgolf84, yes I am interested.

I do not know how to add the docs for using this Operator, but I will study how it is done for other Operators and make an attempt. Any pointers are appreciated!

Update: My PR is ready for review.

@potiuk Is this PR all good to merge? I noticed that there was an error in a workflow run with one of the CI actions failing with status 502 when fetching uv.
