Installing

Requirements

• Minecraft 1.21 or 1.21.1
• Fabric or NeoForge
• Architectury API — required, and not bundled. The mod will refuse to start without it.
• On Fabric, Fabric API as well.

Installation Steps

1. Install Fabric or NeoForge for Minecraft 1.21.1 if you haven't already.
2. Download the build matching your loader from Modrinth or CurseForge — the Fabric and NeoForge jars are published separately, so take the one for your loader.
3. Download Architectury API for the same loader (and Fabric API, on Fabric).
4. Stop your Minecraft instance/server if it is currently running.
5. Copy the jars into your mods folder.
6. Start Minecraft.

Verification

Open the creative inventory and look for the Fixtures & Footnotes tab. If the mod loaded but the tab is missing, something has gone wrong with registration — see Troubleshooting.
