 By default the plugin only fires for MiniMax provider models (IDs matching `minimax/*`, `minimax-cn/*`, etc.). It will not activate for a MiniMax model accessed through OpenRouter or any other provider. To use the plugin with a different model or provider, add the model's ID pattern to `models` in your config — see [CONFIGURATION.md](./CONFIGURATION.md).
 
+## Uninstallation

+
+2. Delete the config files the plugin created:
