I suppose a general config documentation would be quite nice

Bumping this (if that's even a thing on github), I really want to add my own support for farmer's delight!

Hey, I'm yet to do documentation on all the configs for this mod, but here's an example config for custom crop modifiers.

As of version 2.0, the crop config system is now handled by datapacks. You can check this for a how-to example.
