+# 🚀 快速开始指南
+
+## 1️⃣ 安装
+
+```bash
+cd stock-tool
+./install.sh
+```
+
+## 2️⃣ 初始化数据
+
+```bash
+./init_data.sh
+```
+
+## 3️⃣ 运行程序
+
+```bash
+./stock-tool
+# 或
+go run main.go
+```
+
+## 4️⃣ 打开浏览器
+
+访问: http://localhost:8080
+
+## 📱 你会看到什么
+
+### 主界面
+- 📊 股票列表卡片
+- 每张卡片显示:
+  - 股票代码和名称
+  - 当前价格
+  - 涨跌幅
+  - 关键指标（市值、PE、ROE、负债率）
+
+### 点击任意股票
+进入详情页面:
+
+1. **K线图标签** - 展示100天历史走势（蜡烛图）
+2. **技术指标标签** - RSI、MACD、均线系统
+3. **基本面标签** - 收入、利润、ROE等财务数据
+
+### 搜索功能
+- 在搜索框输入: `AAPL` 或 `Apple`
+- 按回车或点击搜索按钮
+- 自动跳转到对应股票详情
+
+### 刷新数据
+- 点击详情页面的"🔄 刷新数据"按钮
+- 重新从API获取最新数据
+
+---
+
+## 🎯 下一步
+
+1. **添加更多股票** - 通过代码或API手动添加
+2. **学习数据结构** - 查看数据库文件 `stock.db`
+3. **集成真实API** - 修改 `main.go` 接入真实的股票数据源
+4. **实现选股策略** - 添加自动筛选功能
+
+## 💡 提示
+
+- 默认使用模拟数据，方便快速上手
+- 数据存储在本地 SQLite 数据库
+- 数据库文件: `stock.db`
+- 可以随时清空数据库重新开始
+
