+
+1. **Check the orchestrator window** for error messages
+2. **Verify Node.js version**: `node --version` (should be 18+)
+3. **Check port availability**: `netstat -ano | findstr :8080`
+4. **Review logs**: Check the orchestrator console window
+
+### Manual Start

+```powershell
+cd orchestrator
+npm run dev
+```

+
+```powershell
+.\scripts\check-status.ps1
+```

+## 📝 Notes
+
+- Orchestrator requires `.env` file (minimal config is fine for development)
+- PostgreSQL and Redis are optional for basic functionality
+- Full database setup requires Docker for PostgreSQL/Redis
