Handbook

Books are defined in datapacks and read in game, so a modpack or map author can ship a guidebook without code. The text preview shows how a page will look while it is written, and a rich text system supports macros for repeated formatting. Entries sit in nested categories that can be bookmarked, and content can be gated behind advancements so players meet it as they progress.

Several page types are ready to use, including text, crafting and image pages, and a template system lets authors define custom page types of their own. Custom visuals and sounds can be attached to a book. Handbook is built for the latest Minecraft versions and works with other mods, and a datagen API lets developers maintain book content through generated JSON instead of editing files by hand, which eases updates to new releases.

The code and datagen are released under the MIT License, while the mod itself is distributed under the Creative Commons Attribution Non Commercial Share Alike 4.0 license and is not open source. It runs on the client and the server, so both sides need it. Files are published for Fabric and NeoForge for 26.1 – 26.1.2, with 1.3.3 for 26.1.2 as the latest file. Source code, an issue tracker and a wiki are linked from the project.
