My friends introduced me to this mod via the Better Minecraft mod pack, and while I quite enjoy it, I am getting very frustrated at the lack of publicly available documentation.

"When do Goblins despawn?"
"What purpose does feeding them serve?"
"Are there End Goblins?"
"When does their inventory restock?"

As the admin of my friend group's server, I would like to either be able to answer them, or direct them to answers.

And before you say it, no, "Join our Discord" is not publicly available documentation.
My server list is already too cluttered with these kinds of servers, and then when I go to leave them to uncluttered the list, I need to play secretary with "which information repository is worth keeping".
Please, just use a GitHub Wiki. I'll even help transcribe information if needed.
