Following #13, it would be great to have an ingame manual.

Prerequisite: #13

Probably using https://github.com/VazkiiMods/Patchouli

This would be ideal but isn't ported to fabric yet: https://github.com/MightyPirates/MarkdownManual

Ah... Looks like Pachouli doesn't use markdown. Might be better to find something else.
