+# 拼多多自动化运营平台
+
+公开的拼多多业务精简版。欢迎所有人克隆、修改、分发代码并提交 Pull Request，代码按 MIT 许可证开放。
+
+保留商品监控、仪表盘、激励看板、营销活动、推广、商品分析、店铺体检、客服质检、上架测算、AI 买家秀和客户端管理等现有模块。部分菜单仍沿用原项目的占位页面。
+
+已删除市场数据整组页面、Claw 对话、skills 管理、平台切换与其他平台演示页，以及对应路由、页面资源、专属配置接口和权限项。首页为仪表盘。保留业务仍使用的模型配置、商品数据查询和自动上架公共服务继续可用；Claw 补全与图搜备用通道已经移除，缺失资料需使用业务接口或手工补充。
+
+## 本地启动
+
+需要 Node.js 22、MySQL 系统库，以及业务实际使用的数据库和外部服务。仓库不包含生产环境配置、密钥、业务数据或原仓库历史。
+
+```bash
+npm --prefix backend ci
+npm --prefix frontend ci
+cp backend/.env.example backend/.env
+```
+
+填写 `backend/.env` 中的连接信息与密钥，分别在两个终端启动：
+
+```bash
+cd backend
+npm run dev
+```
+
+```bash
+cd frontend
+npm run dev
+```
+
+前端默认访问 http://localhost:5173，API 默认代理到 http://localhost:4001，可用 `VITE_API_PROXY_TARGET` 覆盖。首次启动按照安装与设置向导初始化系统。
+
+## 验证与构建
+
+```bash
+npm --prefix backend run check
+npm --prefix frontend run check
+```
+
+前端构建输出位于 `frontend/dist`。部署时需为单页应用配置路由回退，并代理 `/api` 与 `/cubejs-api` 到后端。
+
+启动时会迁移旧侧栏配置，并删除已退役页面的权限和专属设置；业务数据及历史聊天记录不作数据库删表操作。迁移仅作用于实际配置给此实例的系统数据库。
+
+## 参与修改
+
+所有用户均可 Fork 仓库、创建分支并提交 Pull Request。直接推送本仓库需要仓库所有者授予协作者写权限。提交时请说明修改和验证结果，勿提交 `.env`、密码、令牌、数据库备份或真实业务数据。
