+# DevContainer测试应用
+
+这是一个简单的Go应用，用于测试DevContainer功能。
+
+## 功能
+
+- 提供一个基本的HTTP服务器
+- 显示服务器时间和请求信息
+- 包含健康检查端点(/health)
+
+## 使用方法
+
+1. 在DevStar中启动该DevContainer
+2. 容器启动后，访问映射的端口（默认8080）
+3. 你应该能看到一个简单的问候页面
+
+## 开发
+
+DevContainer已经配置好了Go开发环境，包括：
+
+- Go语言支持
+- 代码补全
+- 调试工具
+- 常用命令行工具
+
+只需在VS Code中打开，或通过DevStar提供的编辑器接口访问。
