It also gives instructions on how to set up a venv, which (once I figured out
what that means), seems to work well.

For example, I have a Fooocus directory that contains another Fooocus
directory, which contains the git repo pulled from the master.

In there, I've set up a venv -- so to run Fooocus, I cd into the git
repo directory, then run 

$ ../bin/python3 entry_with_update.py

To get all the requirements installed first, I ran

$ ../bin/pip3 install -r requirements_versions.txt

It was all fairly easy, and it's compartmentalized.
