 ## Notes
 
 - The backend requires `OLLAMA_API_KEY` in environment.
+- Optionally set `OLLAMA_MODEL` to a valid Ollama Cloud model name, for example `llama3` or `gpt-4o-mini`.
 - The frontend stores the access token in `localStorage` for simplicity.
 - OpenAPI docs are available at `http://localhost:8000/docs`.
