Due to the amount of content this mod adds, one would like to be able to configure various things about it a bit easier, without shooting in the dark. Is it possible to create documents regarding configuration of various features in this mod?

What exactly do you need help with? There's a menu ingame where all the features are sorted.

Cave biomes, mainly, as well as larger caves

Enchantment tomes too, I've had some issues in the past trying to add new enchants to them
