Patchouli
by Vazkii
A data-driven in-game documentation and guide book system used by many mods to provide players with mod documentation.
Overview
Patchouli is a library mod created by Vazkii. A data-driven in-game documentation and guide book system used by many mods to provide players with mod documentation. As a library mod it concentrates on shared code that other mods build on, and it has been downloaded around 180 million times, which puts it among the options players reach for in this space.
Patchouli is built for players of mods that ship an in-game guidebook. Patchouli renders data-driven guidebooks, which is why magic and tech mods that include a manual list it as a dependency. It rewards a bit of learning, so expect to spend some time understanding its systems before they click.
The mod is available for Forge, Fabric, and NeoForge, so it fits a range of modpacks and launchers. It currently supports Minecraft 1.20.1 and 1.21.1, spanning the 1.20.1 to 1.21.1 releases. It runs on both the client and the server, so on a multiplayer server every player who connects needs it installed alongside the server itself.

How to install Patchouli
Patchouli supports Forge, Fabric, and NeoForge; pick one loader (you cannot mix them) and install it for your chosen Minecraft version. It is built for Minecraft 1.20.1 and 1.21.1, so make sure your profile uses one of those versions.
- 1Choose and install one mod loader from Forge, Fabric, and NeoForge for a Minecraft version this mod supports (1.20.1 and 1.21.1).
- 2Check the download page for any required libraries. Patchouli lists no hard dependencies here, but it is always worth confirming for your exact version.
- 3Drop the Patchouli .jar file into your instance's mods folder. On a server, place it in the server's mods folder instead, and make sure every connecting player has it too.
- 4Launch the game with that loader profile and confirm Patchouli appears in the in-game mods list; if it does not load, re-check the loader, the Minecraft version, and any library requirements.
Supported Minecraft versions: 1.20.1 and 1.21.1. Always download the build that matches your version exactly, as mod files are version-specific.

Because it ships for both Fabric and Forge-family loaders, it slots into most popular modpacks regardless of which side they are built on.
As a library mod, Patchouli adds no content of its own and has a negligible footprint, it exists to support the mods that depend on it.
If you are comparing options, similar mods include Modonomicon and Guidebook. They cover comparable ground, so the right choice usually comes down to your loader, version, and the rest of your pack.
