+## Quick start (Docker)
+
+If you prefer to run the chatbot in a container instead of a local virtual-env, use the provided `Dockerfile`.
+
+```bash
+# 1. Build the image (tagged "streamlit-chatbot")
+docker build -t streamlit-chatbot .
+
+# 2. Run the container and expose the app on http://localhost:8501
+docker run --rm -it -e PORT=8501 -p 8501:8501 streamlit-chatbot
+```
+
+The container entrypoint launches Streamlit on the port given by the `PORT` environment variable (the same variable Hugging Face uses). By passing `-e PORT=8501` and mapping `-p 8501:8501`, you can access the interface in your browser at `http://localhost:8501`.
