Thaumonomicon-Style In-Game Documentation

Modonomicon is an in-game documentation mod inspired by Thaumcraft's Thaumonomicon and Patchouli, and aims to provide the best of both, with some unique flavors.

Some of the most interesting features are:

  • Fully data-driven, all books are created via datapack (that means both Modpacks and Mods can add books).
  • Patchouli-like Multiblocks (but fully data driven)
  • Made to be extensible, mods can add new features, such as recipe pages for mod-specific crafting methods.
  • "Quest/Advancement"-style 2D view to navigate the content, as seen in the Thaumonomicon.
  • Extensible condition system to unlock entries.
  • Easy styling of content with (extended) Markdown syntax.
  • Various page types to display text, recipes, images, items and more.

How to install Modonomicon

With Millida Launcher

  1. Install Millida Launcher

    The launcher is free: download it at millida.net/launcher and sign in with any nickname.

  2. Click “Install” on this page

    The launcher opens and installs the mod for Minecraft 1.21.1–26.3 on Fabric, Forge or NeoForge automatically.

  3. Launch the game

    A profile with it appears in the launcher: click “Play”.

Manually

  1. Install Fabric, Forge or NeoForge

    The loader must match the game version of the mod file, for example Minecraft 26.3. After installing it, a separate profile appears in your launcher.

  2. Download the file for your version

    In the version list above, pick the file modonomicon-26.3-fabric-2.17.3.jar (3.2 MB) for your game version and loader.

  3. Put it in the mods folder

    The folder is inside .minecraft (Windows: %appdata%\.minecraft\mods). If it does not exist, create it.

  4. Launch the loader profile

    Open “Mods” in the main menu: Modonomicon should be in the list.

On a server

  1. A server on Fabric, Forge or NeoForge

    The mod only works on a server with the same loader and game version, for example 26.3.

  2. File goes into the server’s mods folder

    Stop the server, put the mod file into the mods folder and start the server again.

  3. Use the “To server” button

    On Millida Hosting, the button at the top of the page uploads the file to your server and restarts it for you.
