Great first genie PR! I added some comments

Also don't forget to make sure your build is successful, i think there's just some formatting to adjust in your code: https://github.com/Sage-Bionetworks/Genie/actions/runs/8237606927/job/22526728071?pr=553

If you have black installed, you can just run black on everything using black . (which will auto-lint your code) then commit and push the formatting changes.
