 ## How to use?
 
+### 
+- The nacos/v2 version of hertz does not currently support creating multiple port examples in the same group multiple times.
+- Service registration and discovery in nacos/v2 is compatible with previous versions.
+- `CustomLogger` type in constant.ClientConfig has been removed in nacos-sdk-go v2. Instead, use the `(github.com/nacos-group/nacos-sdk-go/v2/common/logger).SetLogger` to customize the log.
+- nacos/v2 only supports nacos 2.X version.

 ## 这个项目应当如何使用?
 
+### 注意
+
+- nacos/v2 版本中 hertz 目前不支持多次在同分组下创建多端口示例
+- nacos/v2 的服务注册与发现和先前的版本兼容
+- nacos-sdk-go v2 版本中 constant.ClientConfig 中 CustomLogger 类型被移除, 转而使用 (github.com/nacos-group/nacos-sdk-go/v2/common/logger).SetLogger 方法进行日志自定义
+- nacos/v2 只支持 nacos 2.X 版本
