+- Create a `.env` file with your API key (automatically uses `$GEMINI_API_KEY` if already in your environment)
+- **Automatically build the Docker image for you** - no manual build needed!
+- Clean up any existing containers/images before building fresh
 - **Display the exact Claude Desktop configuration to copy** - save this output!
