📖 Vellumli

Accessible, data-driven, dependency-free documentation for Minecraft.

✨ Overview

Vellumli lets modders and pack makers write in-game guidebooks for their content using nothing but data files — no Java, no dependency on any specific mod. Entries, categories, and multiblock/crafting-turn-in pages are defined in JSON and rendered as a fully navigable in-game book.

The mod is currently in early development (0.0.0-beta.1). The core book engine and page types are being ported first; the full feature set below reflects the target functionality inherited from Patchouli and will be enabled progressively across beta releases.

🎯 Planned Features

📚 Data-Driven Books

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

🧭 In-Game Navigation

A fully-featured book GUI with category browsing, entry search, bookmarks and a landing page, so players can find the documentation they need without leaving the game.

🧩 Rich Page Types

Built-in page types for text, crafting/smelting/smithing recipe turn-ins, images, spotlight items, relations, quests and multiblock structures — enough to document almost any mod without custom code.

🔓 Advancement-Gated Content

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

🗺️ Multiblock & Structure Preview

Preview multiblock structures in 3D directly from the book, including a "ready to build" check against the player's current world.

🧩 Dependency-Free by Design

Vellumli itself has no gameplay dependency on other mods — any mod (or datapack) can add its own book without needing to add code, only data.

📋 Requirements

🎮 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.
3. Author your own book by adding category/entry/page JSON files under a datapack, as documented in the wiki (coming soon).
