+## 本地运行（默认数据库路径）
+- 默认数据库：`sqlite:///data/data.db`（项目根目录下的 `data/data.db`）
+- 启动：
+  ```powershell
+  $env:PORT=57778; $env:ADMIN_TOKEN="<你的口令>"; python backend/app.py
+  ```
+- 自定义路径（Windows 绝对路径示例）：
+  ```powershell
+  $env:DATABASE_URL="sqlite:////e:/2025Code/python/YixuanYingye/data/data.db"; python backend/app.py
+  ```

 ## 环境优化（最优解）
 - 基础镜像切换为 `python:3.11-alpine`，构建更快、体积更小
 - 依赖安装走腾讯云 PyPI 镜像：`PIP_INDEX_URL=https://mirrors.cloud.tencent.com/pypi/simple`
