Disco
Disco is a modular system for loading music discs into Minecraft. By default, the mod doesn't add any ready-made musical compositions - this capability is entirely up to you. You prepare the necessary resources yourself, including audio files, textures, and localizations, and Disco automatically registers them as individual disc items that can be played in the game.
How to Use
The most convenient way to create addons is to use the Disco web application. This tool allows you to store multiple drafts, convert resources into the required formats, and compile ready addon files all in one place.
If you prefer a manual approach, check out the guide on the wiki to learn how to create addons yourself.
To install a ready addon, simply place its file in the Fabric mods folder.
