# Publish a cartridge

<Steps>

### Create the directory

Copy `cartridges/_template` to `cartridges/your-game`.

### Add the cartridge

Replace `game.tynt`, complete `cartridge.json`, and write the cartridge README.

### Capture the cover

Add a 320 × 288 nearest-neighbor `cover.png` captured from the 160 × 144 game canvas.

### Verify the repository

Run `bun run check` from the repository root and submit the complete cartridge directory in one pull request.

</Steps>

All submitted cartridge source and artwork must use the MIT License and declare `"license": "MIT"` in `cartridge.json`. By submitting a cartridge, you confirm that you created its contents or have permission to distribute them under MIT.

The gallery generator discovers every valid `cartridges/<slug>/` directory automatically. Contributors never edit a central registry. Keep unrelated application, dependency, workflow, and configuration changes out of a cartridge submission.
