+# Docker Setup
+
+This project combines a Next.js frontend and a Python langgraph agent.
+
+## Quick Start
+
+```bash
+# Start both applications
+docker compose up
+
+# Rebuild and start
+docker compose build && docker compose up
+
+# Run in background
+docker compose up -d
+
+# Stop containers
+docker compose down
+
+```
+
+## Access Points
+
+- Frontend: http://localhost:3000
+- Agent: http://localhost:8123
+
+## Logs
+
+```bash
+# All services
+docker compose logs
+
+# Specific service
+docker compose logs frontend
+docker compose logs agent
+
+# Follow logs
+docker compose logs -f
+```
+
+## Troubleshooting
+
+The agent container auto-restarts up to 5 times if it fails.
+Check logs with `docker compose logs agent`.
