All I can tell you, @adw, is that when I tried to use the live instructions, I hit a step where I couldn’t make sense of it. It was “endgame” for me until @rustybird threw me a link to the github version. The thread is here, along with a couple of suggestions from me that I guess I should have contributed on github.
It would be really great to get that updated version live. I can only imagine it would be pretty stressful time if you had to use this emergency access for real - bad instructions would be the last thing you need.
