+```
+
+---
+
+## 一、后端服务
+
+### 前置要求
+
+- Python 3.10+（[下载地址](https://www.python.org/downloads/)）
+
+### 1. 安装依赖
+
+```bash
+cd back
+
+# 创建虚拟环境（推荐）
+python -m venv venv
+
+# 激活虚拟环境
+# macOS / Linux
+source venv/bin/activate
+
+# Windows
+venv\Scripts\activate
+
+# 安装依赖
+pip install -r requirements.txt
+```
+
+### 2. 启动服务
+
+```bash
+# 确保在 back 目录且虚拟环境已激活
+source venv/bin/activate
+
+uvicorn main:app --reload --port 8000
+```
+
+- `main:app` — `main.py` 中的 `app` 实例
+- `--reload` — 开发模式，代码修改自动重启
+- `--port 8000` — 服务端口
+
+### 3. 验证
+
+- API 文档：[http://127.0.0.1:8000/docs](http://127.0.0.1:8000/docs)
+- LOF 数据接口：[http://127.0.0.1:8000/api/lof](http://127.0.0.1:8000/api/lof)
+
+---
+
+## 二、前端服务
+
+> **前置要求**：电脑上需安装 [nvm](https://github.com/nvm-sh/nvm)（Node 版本管理工具）。
+
+### 1. 切换 Node 版本
+
+前端项目通过 `.nvmrc` 文件锁定 Node 版本（当前为 `v22.21.1`）。
+
+**macOS / Linux：**
+
+```bash
+cd front/vite-project
+
+# 自动读取 .nvmrc 中的版本并切换
+nvm use
+
+# 如果该版本未安装，先安装再切换
+nvm install
+nvm use
+```
+
+**Windows：**
+
+Windows 版 nvm 不支持自动读取 `.nvmrc`，需显式指定版本号：
+
+```bash
+cd front/vite-project
+
+nvm install v22.21.1
+nvm use v22.21.1
+```
+
+### 2. 安装依赖
+
+```bash
+npm install
+```
+
+### 3. 启动服务
+
+```bash
+npm run dev
+```
+
+默认运行在 [http://localhost:5173](http://localhost:5173)
+
+### 3. 构建生产包
+
+```bash
+npm run build
+```
+
+---
+
+## 三、接口说明
+
+### GET `/api/lof`
+
+获取全量 LOF 实时数据。
+
+**返回字段：**
+
+| 字段 | 类型 | 说明 |
+|---|---|---|
+| `fundCode` | string | 基金代码 |
+| `fundName` | string | 基金名称 |
+| `tradePrice` | number | 最新交易价 |
+| `increaseRate` | number | 涨跌幅（%）|
+| `netValue` | number | 最新净值 |
+| `premiumRate` | number | 溢价率（%）|
+| `purchaseLimit` | string | 日申购限额 |
+| `purchaseStatus` | string | 申购状态 |
+
+**限额显示规则：**
+- `不限` — 日限额 ≥ 1 亿
+- `暂停申购` — 日限额为 0
+- `xx元/日` — 日限额 < 1 万
+- `xx万/日` — 日限额 ≥ 1 万
+
+---
+
+## 四、常见问题
+
+### 1. 后端端口被占用
+
+```bash
+# 查找占用 8000 端口的进程并结束
+lsof -ti:8000 | xargs kill -9
+```
+
+### 2. 前端请求后端接口失败
+
+确保后端服务已启动，且 CORS 配置正确（默认允许所有来源）。
