A little more before you start.

Does the website install software on my computer?

The install button copies the official command. You run it in your agent or terminal. The website cannot access your games or install software directly.

Which games can I mod?

The toolkit includes playbooks for many game engines. Compatibility depends on the game, version, and modding route. Read the project documentation before starting.

Can I upload and download mods for free?

Yes. Downloads are public; publishing requires a free account. Upload a ZIP with your own mod files and clear instructions. AI asset providers may charge separately.
