How to install

  1. Click Export .zip. Save the file somewhere you can find it.
  2. Open your Minecraft world's save folder. On Windows it's typically %appdata%/.minecraft/saves/<world>/datapacks/. On macOS it's ~/Library/Application Support/minecraft/saves/<world>/datapacks/.
  3. Drop the .zip directly into that folder. Don't extract it — Minecraft reads the zip as-is.
  4. Open the world and run /reload in chat. Verify with /datapack list.
