@dwhswenson looking for guidance on if this is a bit clearer of an image around what is uses in which action. Open to improvements!

[ethanholz]

Agreed, more than happy to add these additions for clarity!

[ethanholz]

Added some new areas for clarity. The CI probably shouldn't update unless we are actively updating code, codecov and pytest runs are not necessary when updating docs alone.

@dwhswenson this is ready for re-review.
