Hi @kentbull!
Thanks for this [draft] PR! 💯
It looks good for the most of it, just it seems that the CI gate for the tutorial is failing. And one note might need updating (depending on the path that we choose).

You can test the same gate locally as (I've just verified it still works on CPython 3.10):

tox -e asgilook

This note might need to be updated or even removed altogether if it is no longer needed. How can we hook in fakeredis for testing then though? (Monkey-patching or mocking might work too.)

[kentbull]

with the latest update I made the redis_from_url function is still used. I added a wrapper function to config.py to change as little as possible. Monkey patching still works.

[kentbull]

Tests pass, though coverage is not at 100%.

[vytas7]

I've tweaked your code slightly @kentbull, and retested it manually. Now everything seems to pass and work for me.
