 ### 方式二：通过指定proto生成rpc服务
 
 * 生成proto模板
 
-  ```Bash
-  goctl rpc template -o=user.proto
-  ```
-
-  ```golang
-  syntax = "proto3";
-
-  package remote;
-
-  message Request {
-    // 用户名
-    string username = 1;
-    // 用户密码
-    string password = 2;
-  }
-
-  message Response {
-    // 用户名称
-    string name = 1;
-    // 用户性别
-    string gender = 2;
-  }
-
-  service User {
-    // 登录
-    rpc Login(Request)returns(Response);
-  }
-  ```
-
-* 生成rpc服务代码
-
-  ```Bash
-  goctl rpc proto -src=user.proto
-  ```
-
-## 准备工作
-
-* 安装了go环境
-* 安装了protoc&protoc-gen-go，并且已经设置环境变量
-* 更多问题请见 <a href="#注意事项">注意事项</a>
-
-## 用法
-
-### rpc服务生成用法
-
 ```Bash
-goctl rpc proto -h
+$ goctl rpc template -o=user.proto
 ```
+  
+```proto
+syntax = "proto3";
 
-```Bash
-NAME:
-   goctl rpc proto - generate rpc from proto
+package user;
+option go_package="./user";
 
-USAGE:
-   goctl rpc proto [command options] [arguments...]
+message Request {
+  string ping = 1;
+}
 
-OPTIONS:
-   --src value, -s value         the file path of the proto source file
-   --proto_path value, -I value  native command of protoc, specify the directory in which to search for imports. [optional]
-   --go_opt value                native command of protoc-gen-go, specify the mapping from proto to go, eg --go_opt=proto_import=go_package_import. [optional]
-   --dir value, -d value         the target path of the code
-   --style value                 the file naming format, see [https://github.com/zeromicro/go-zero/tree/master/tools/goctl/config/readme.md]
-   --idea                        whether the command execution environment is from idea plugin. [optional]
+message Response {
+  string pong = 1;
+}
 
+service User {
+  rpc Ping(Request) returns(Response);
+}
 ```
+  
 
-### 参数说明
-
-* --src 必填，proto数据源，目前暂时支持单个proto文件生成
-* --proto_path 可选，protoc原生子命令，用于指定proto import从何处查找，可指定多个路径,如`goctl rpc -I={path1} -I={path2} ...`
-  ,在没有import时可不填。当前proto路径不用指定，已经内置，`-I`的详细用法请参考`protoc -h`
-* --go_opt 可选，protoc-gen-go插件原生flag，用于指定go_package
-* --dir 可选，默认为proto文件所在目录，生成代码的目标目录
-* --style 可选，指定生成文件名的命名风格
-* --idea 可选，是否为idea插件中执行，终端执行可以忽略
-
-
-### 开发人员需要做什么
-
-关注业务代码编写，将重复性、与业务无关的工作交给goctl，生成好rpc服务代码后，开发人员仅需要修改
-
-* 服务中的配置文件编写(etc/xx.json、internal/config/config.go)
-* 服务中业务逻辑编写(internal/logic/xxlogic.go)
-* 服务中资源上下文的编写(internal/svc/servicecontext.go)
-
-
-### 注意事项
-
-* proto不支持暂多文件同时生成
-* proto不支持外部依赖包引入，message不支持inline
-* 目前main文件、shared文件、handler文件会被强制覆盖，而和开发人员手动需要编写的则不会覆盖生成，这一类在代码头部均有
+* 生成rpc服务代码
 
-```shell script
-    // Code generated by goctl. DO NOT EDIT!
-    // Source: xxx.proto
+```bash
+$ goctl rpc protoc  user.proto --go_out=. --go-grpc_out=. --zrpc_out=.
 ```
 
-的标识，请注意不要将也写业务性代码写在里面。
-
-## proto import
-* 对于rpc中的requestType和returnType必须在main proto文件定义，对于proto中的message可以像protoc一样import其他proto文件。
 
-proto示例:
