About this project

What does Vellumli add?

📖 Vellumli

Accessible, data-driven, dependency-free in-game guidebooks — no Java required.

NeoForge Minecraft 26.2 and 1.21.1 Library CC BY-NC-SA 3.0

✨ Overview

Vellumli lets modders and pack makers write in-game guidebooks for their content using nothing but data files — categories, entries and pages are defined in JSON and rendered as a fully navigable in-game book. It has no gameplay dependency on any other mod: any mod or datapack can ship its own book by adding data, not code.

📚 Data-Driven Books

Define categories, entries and pages entirely as JSON. Books, categories and entries can be added or overridden by datapacks and resource packs without touching Java code.

🧭 Rich Page Types

Built-in page types for text, crafting / smelting / smithing / blasting / campfire recipe turn-ins, images, spotlight items, entity previews, relations, links and quests — enough to document almost any mod without custom code. Custom component and template systems allow reusable, parameterised layouts.

🧩 In-Game Navigation

A full book GUI with a landing page, category browsing, entry search, bookmarks and history — players find the documentation they need without leaving the game.

🔓 Advancement-Gated Content

Lock entries and categories behind advancements so documentation unlocks progressively as the player advances.

🧱 Mod Structure

Area What it provides
api The public surface other mods build against: the book/entry/page model, custom-component and multiblock hooks, and the render-context interfaces.
common/book Book loading, the datapack/resourcepack registry, and folder discovery.
client/book The book GUI, the page renderers, text layout and the bookmark/history system.
common/item The guide-book item, its book data component and completion model property.
compat/jei JEI subtype interpreter so each mod's book is a distinct, searchable ingredient. Optional.
xplat / neoforge The platform abstraction layer and its NeoForge implementation (networking, mod list, events).

📋 Requirements

Minecraft / NeoForge / Java see Available Versions below
Dependencies None — Vellumli is dependency-free by design
JEI Optional (searchable-book compat only)
Side Client and Server (required on both)

📦 Available Versions

Minecraft NeoForge Java Latest build Status
26.2 26.2.0.57+ 21 1.2.0 Stable
1.21.1 21.1.249+ 21 1.0.0 Stable

Both versions share this CurseForge project. Pick the file that matches your Minecraft version.

🎮 How to Use

  1. Install the mod on both client and server.
  2. Craft or obtain a book item associated with a Vellumli-powered book (added by another mod or your datapack).
  3. Author your own book by adding category / entry / page JSON files under a datapack — the format matches Patchouli's.
