Well, as someone who has been trying to launch a functioning Lemmy instance for nearly a year now, I can tell you, knowing not the slightest thing about funkwhale, that I would eat my hat if the documentation isn't an all but absent shit show.
My favorite part was learning that my domain was creating a completely new cert from lets encrypt with each deployment and no way of recovering them at all. So after 5 attempts, you have to wait 60 days (or whatever) for them to expire. That was awesome. I messaged the devs about that one and they literally said "we didn't think of that"... ๐
And so much shit goes tits up if you don't deploy it perfectly the very first time. Don't get me wrong, I love the fediverse, but JTFC I hate the fucking fediverse.
