 Check out the configuration reference at https://huggingface.co/docs/hub/spaces-config-reference
+
+## Docker Setup
+
+This project uses Docker for containerization. The default configuration runs on port 7860 which is compatible with Hugging Face Spaces.
+
+### Running with Docker
+
+```bash
+# Build and start the container
+docker compose up app
+
+# For development with hot-reloading
+docker compose up dev
+```
+
+### Environment Variables
+
+- `PORT`: The port on which the server will run (default: 7860)
+
+### Troubleshooting
+
+If you encounter issues with the container starting:
+
+1. Check if the port 7860 is already in use
+2. Ensure the application built successfully
+3. Review the container logs for more details
