+
+## 使用
+
+### gRPC service 定义
+
+例如，假设您有两个 proto 文件（如下所示），每个包含一个 service。
+通过执行 kitex 命令，可以自动生成对应的代码。
+
+```protobuf
+// File1：servicea.proto
+syntax = "proto3";
+
+option go_package = "myservice";
+
+package myservice;
+
+service ServiceA {
+  rpc EchoA (stream RequestA) returns (stream ReplyA) {}
+}
+
+message RequestA {
+  ...
+}
+
+message ReplyA {
+  ...
+}
+
+
+// File2：serviceb.proto
+syntax = "proto3";
+
+option go_package = "myservice";
+
+package myservice;
+
+service ServiceB {
+  rpc EchoB (stream RequestB) returns (stream ReplyB) {}
+}
+
+message RequestB {
+  ...
+}
+
+message ReplyB {
+  ...
+}
+```
+
+### 如何在一个 server 上注册多个 service
+
+在一个 server 上注册多个 service 是一个简单的过程。
+
+首先，创建一个 server。然后，通过调用该 server 上的 `RegisterService` 函数，就可以注册 service 了。
+
+可以在同一台 server 上提供多个 service，根据需要注册多个 service。
+
+```golang
+package main
+
+import (
+   "github.com/cloudwego/kitex/pkg/server"
+
+   servicea "your_servicea_kitex_gen_path"
+   serviceb "your_serviceb_kitex_gen_path"
+)
+
+func main() {
+   // create a server by calling server.NewServer
+   svr := server.NewServer(your_server_option)
+   // register multi-service on a server
+   err := svr.RegisterService(servicea.NewServiceInfo(), new(ServiceAImpl))
+   err := svr.RegisterService(serviceb.NewServiceInfo(), new(ServiceBImpl))
+
+   err := svr.Run()
+
+   if err != nil {
+      logs.Error("%s", err.Error())
+   }
+   logs.Stop()
+}
+```
