+# MiniSwap CLI 工具使用指南
+
+这个 CLI 工具让你可以通过命令行操作和测试 MiniSwapAMM 合约的所有功能，无需前端界面。
+
+## 前置条件
+
+1. 确保已经部署了合约：
+```bash
+npm run deploy
+```
+
+2. 确保本地网络正在运行：
+```bash
+npm run node
+```
+
+## 快速开始
+
+### 方法1: 交互式 CLI 工具
+
+启动交互式命令行界面：
+```bash
+npm run cli
+```
+
+这将启动一个交互式界面，你可以输入命令来操作合约。
+
+### 方法2: 测试网络连接
+
+如果遇到连接问题，可以先运行连接测试：
+```bash
+npm run test-connection
+```
+
+这会测试网络连接和合约加载是否正常。
+
+### 方法3: 运行完整测试场景
+
+运行预设的完整测试场景：
+```bash
+npm run test-scenario
+```
+
+这会自动执行一系列操作，演示 AMM 的所有功能。
+
+## CLI 命令详解
+
+### 基本信息查询
+
+- `accounts` - 显示所有可用账户
+- `switch <index>` - 切换到指定账户（例如：`switch 1`）
+- `balances` - 查看当前账户的所有代币余额
+- `reserves` - 查看 AMM 池的储备量和价格信息
+
+### 代币操作
+
+- `mint [amount]` - 铸造测试代币（默认 1000 个）
+  - 例如：`mint 500` 铸造 500 个代币
+- `approve [amount]` - 授权代币给 AMM 合约（默认 10000 个）
+  - 例如：`approve 5000` 授权 5000 个代币
+
+### 流动性操作
+
+- `add <amountA> <amountB> [slippage]` - 添加流动性
+  - 例如：`add 1000 2000 1` 添加 1000 TKA + 2000 TKB，允许 1% 滑点
+- `remove <liquidity> [slippage]` - 移除流动性
+  - 例如：`remove 500 1` 移除 500 个 LP 代币，允许 1% 滑点
+
+### 代币交换
+
+- `swapAB <amount> [slippage]` - 将 TokenA 交换为 TokenB
+  - 例如：`swapAB 100 1` 用 100 TKA 交换 TKB，允许 1% 滑点
+- `swapBA <amount> [slippage]` - 将 TokenB 交换为 TokenA
+  - 例如：`swapBA 50 1` 用 50 TKB 交换 TKA，允许 1% 滑点
+
+### 价格计算
+
+- `calc <amount> <direction>` - 计算交换价格
+  - `calc 100 a2b` - 计算 100 TKA 能换多少 TKB
+  - `calc 50 b2a` - 计算 50 TKB 能换多少 TKA
+
+### 其他命令
+
+- `help` - 显示帮助信息
+- `exit` - 退出程序
+
+## 使用示例
+
+以下是一个完整的操作流程示例：
+
+```bash
+# 启动 CLI
+npm run cli
+
+# 查看当前账户余额
+> balances
+
+# 铸造一些测试代币
+> mint 5000
+
+# 授权代币给 AMM 合约
+> approve 10000
+
+# 添加初始流动性（1000 TKA + 2000 TKB）
+> add 1000 2000
+
+# 查看池子状态
+> reserves
+
+# 切换到另一个账户
+> switch 1
+
+# 为新账户铸造代币
+> mint 3000
+> approve 5000
+
+# 进行代币交换
+> swapAB 100 1
+
+# 查看交换后的余额
+> balances
+> reserves
+
+# 计算交换价格
+> calc 50 a2b
+
+# 退出
+> exit
+```
+
+## 滑点保护
+
+所有涉及交换和流动性操作的命令都支持滑点保护参数：
+- 滑点参数以百分比形式输入（例如：1 表示 1%）
+- 如果不指定，默认使用 1% 的滑点保护
+- 滑点保护可以防止因价格变动导致的不利交易
+
+## 注意事项
+
+1. **网络连接**：确保本地 Hardhat 网络正在运行
+2. **代币授权**：在添加流动性或交换代币前，必须先授权代币给 AMM 合约
+3. **账户管理**：可以使用 `switch` 命令在不同账户间切换，模拟多用户操作
+4. **交易确认**：每个交易都会等待区块确认，可能需要几秒钟
+5. **错误处理**：如果操作失败，CLI 会显示详细的错误信息
+
+## 故障排除
+
+### 常见错误及解决方法
+
+1. **"could not decode result data" 错误**
+   - 原因：CLI 工具连接的网络与合约部署的网络不一致
+   - 解决：确保先运行 `npm run node`，然后运行 `npm run deploy`，最后运行 `npm run cli`
+
+2. **"合约地址文件不存在" 错误**
+   - 解决：运行 `npm run deploy` 重新部署合约
+
+3. **"网络连接失败" 错误**
+   - 解决：确保本地网络正在运行 `npm run node`
+
+4. **"合约验证失败" 错误**
+   - 原因：合约可能没有正确部署或网络不匹配
+   - 解决：重新部署合约 `npm run deploy`
+
+5. **其他问题**
+   - **代币不足**：使用 `mint` 命令铸造更多代币
+   - **未授权代币**：使用 `approve` 命令授权代币
+   - **滑点过大**：增加滑点保护参数或减少交换数量
+
+### 完整重置流程
+
+如果遇到无法解决的问题，可以完全重置：
+
+```bash
+# 1. 停止当前网络 (Ctrl+C)
+# 2. 重新启动网络
+npm run node
+
+# 3. 重新部署合约（新终端）
+npm run deploy
+
+# 4. 启动 CLI
+npm run cli
+```
+
+## 高级功能
+
+- **批量测试**：使用 `npm run test-scenario` 运行完整的测试场景
+- **多账户操作**：使用 `switch` 命令模拟多用户环境
+- **价格影响分析**：通过连续小额交换观察价格变化
+- **流动性管理**：添加和移除流动性来观察对价格的影响
