Loopop's guide looks interesting, but to unlock the book I had to join (for free) the Patreon channel. Then it immediately tells me that to unlock the book I have to become a paid member.
It turns out that the free tier only gets you notifications when new content is published; to read that content, you have to pay.
I wouldn't mind paying, but dislike the bait and switch approach.
Come on, you can join for one month, download the up to date version and leave again. Not too much asked for such a ressource.
His patreon is really explicit about what you get for what tiers. I get that the patreon ui is pretty confusing, but that’s not his fault
