I don't know my version or loader


Handbook
Datapack-driven in-game documentation for Minecraft mods. For mod and modpack developers who are tired of not being able to support the latest versions, as Patchouli and other derivatives often take six months or longer to update, or only supports a single modloader.
This mod exists specifically to support the latest versions of Minecraft and is very focused on in-game mod content. There is a robust datagen API that lets mod developers maintain book content without manually editing and curating JSON files, making it easy to update to new Minecraft versions. Examples of this in action are for Homeostatic and Survivalist Essentials
To be clear, this mod is a fork of Patchouli and Patchouli Provider. It is recommended to use those as a first alternative if they exist for the target Minecraft version you are modding for. This exists only to move forward without waiting.
