-- Docker and Docker Compose (for agent services)
+- [uv](https://docs.astral.sh/uv/) installed (for running agents natively)
 - [OpenAI API key](https://platform.openai.com/api-keys)
 - [FlightAware AeroAPI key](https://www.flightaware.com/aeroapi/portal)
+- Docker and Docker Compose (optional, only needed for `--with-ui`)
 
 > **Note:** You'll need to obtain a FlightAware AeroAPI key for live flight data. Visit [https://www.flightaware.com/aeroapi/portal](https://www.flightaware.com/aeroapi/portal) to get your API key.
