+# Simple C++ CMake Project
 
+这是一个简单的 C++17 项目，使用 CMake 构建系统。
+
+## 项目结构

+```
+
+## 编译步骤
+
+### 1. 创建构建目录
+```bash
+mkdir build
+cd build
+```
+
+### 2. 配置 CMake
+```bash
+cmake ..
+```
+
+### 3. 编译项目
+```bash
+cmake --build .
+```
+
+或者使用平台特定的编译命令：
+```bash
+make  # Linux/macOS
+```
+
+### 4. 运行主程序
+编译完成后，可执行文件位于 `build/bin/` 目录下：
+
+```bash
+# 运行主程序
+./build/bin/main_app
+
+# 运行测试
+./build/bin/basic_test
+```
+
+## 功能说明
+
+- **main_app**: 主程序，演示基本的应用程序功能
+- **basic_test**: 基本测试程序，验证核心功能
+
+## 依赖要求
+
+- CMake 3.10 或更高版本
+- 支持 C++17 的编译器（如 GCC 7+, Clang 5+, MSVC 2017+）
