+## 数据预置与迁移
+- 首次启动自动导入（DB为空时）：
+  1. 如果存在 `/app/data/import.csv`，优先导入该文件
+  2. 否则导入镜像内 `/app/init/revenue.csv`（可将 `seed/revenue.sample.csv` 重命名为 `revenue.csv`）
+- CSV格式：
+  ```
+  date,amount
+  2025-12-01,12345.67
+  2025-12-02,11890.12
+  ```
+- 手动导入接口：
+  ```bash
+  curl -X POST http://<服务器>:57778/api/admin/import \
+    -H "X-Admin-Token: $ADMIN_TOKEN" -H "Content-Type: text/csv" \
+    --data-binary @revenue.csv
+  ```
+
+## 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`
+- 自动数据导入：环境变量 `AUTO_IMPORT_ON_START=1`，启动时按顺序导入
+  1. `/app/data/import.csv`（宿主机 `./data/import.csv`）
+  2. `/app/init/revenue.csv`（仓库 `seed/revenue.csv`）
+  3. `/app/init/revenue.sample.csv`
+
 ## 生产建议
 - 建议使用反向代理（Nginx）暴露 `5000` 端口，并开启 gzip
 - 建议通过 `docker-compose` 的 `restart: unless-stopped` 保持服务稳定
