Yesterday was day 2 of my PSF grant. I continued to work on developer documentation that focused on people new to Python's development.
But the really cool thing is that Georg Brandl wrote a commit hook so that the devguide is online while it is being developed! Now this might not be the permanent URL so don't be shocked if the link stops working. But it is nice to have it up so people can easily peruse the docs while I am writing.
As for new docs written yesterday, I managed to get Lifecycle of a Patch done which explains the process of creating and submitting a patch. I also got instructions on how to run the test suite and writing tests for it finished.
