+## 后台启动脚本
+
+如果你不想用 Docker，可以直接用项目根目录下的脚本把前后端挂到后台：
+
+```bash
+chmod +x start.sh stop.sh status.sh
+./start.sh
+```
+
+脚本会做这些事：
+
+- 后台启动 FastAPI，默认端口 `8000`
+- 后台启动 Vite，默认端口 `8451`
+- 把 PID 写到 `.run/`
+- 把日志写到 `logs/`
+
+常用命令：
+
+```bash
+./status.sh
+./stop.sh
+tail -f logs/backend.log
+tail -f logs/frontend.log
+```
+
+如果你要改端口，可以在启动前传环境变量，前端代理也会自动跟着后端端口变化：
+
+```bash
+BACKEND_PORT=9000 FRONTEND_PORT=8451 ./start.sh
+```
+
 ## Docker 启动
 
 如果你希望在 Ubuntu 24.04 或其他装有 Docker 的环境中快速运行，直接使用：
