- 2Check the download page for any required libraries. Tetra lists no hard dependencies here, but it is always worth confirming for your exact version.
- 3Drop the Tetra .jar file into your instance's mods folder. On a server, place it in the server's mods folder instead, and make sure every connecting player has it too.
- 4Launch the game with that loader profile and confirm Tetra appears in the in-game mods list; if it does not load, re-check the loader, the Minecraft version, and any library requirements.
