+## Overview
+
+After completing the <a href="/docs/tasks/installation/goctl" target="_blank">goctl installation</a>, we can create a minimal HTTP service to get an overview of goctl's go-zero api service.
+
+## Task Targets
+
+1. Learn how to create a minimized HTTP service using goctl
+1. Preliminary understanding of the project structure of go-zero
+
+
+## Preparing
+
+1. <a href="/docs/tasks" target="_blank">Complete golang installation</a>
+1. <a href="/docs/tasks/installation/goctl" target="_blank">Complete goctl installation</a>
+
+## Code Generation
+
+```shell
+# Create workspaces and enter the directory
+$ mkdir -p ~/workspace/api && cd ~/workspace/api
+# Execute instructions generated demo service
+$ goctl api new demo
+Done.
+```
+After executing the instruction, a demo directory will be generated under the current directory that contains a minimized HTTP service and we will check the directory structure of the service.
+
+```shell
+$ cd ~/workspace/api/demo
+$ ls
+demo.api demo.go  etc      go.mod   internal
+$ tree
+.
+├── demo.api
+├── demo.go
+├── etc

+
+:::note
+API, RPC, Job Directory structure is similar to what the go-zero project structure can look at <a href="/docs/concepts/layout">Project Structure</a>
+:::
+
+## Write simple logic code
+
+After completing the above code generation, we can find `~/workspace/api/demo/internal/logic/demologic.go` files, add c odes between line `27` and `28`  :
+
+```go
+resp = new(types.Response)
+resp.Message = req.Name
+```
+
+## Start service
+
+After writing the above code, we can start the service with the following instructions：
+
+```shell
+# Enter service directory
+$ cd ~/workspace/api/demo
+# to organize dependencies
+$ go mod tidy
+# Run go program
+$ go run demo.go
+```
+
+When you see the following output `Starting server at 0.0.0.0.0:888...`indicates that the service has been successfully started, then we come to visit the HTTP service.

+title: api file format
+slug: /docs/tasks/cli/api-format
+---
+
+## Overview
+
+After the api file is written, the content of our api is uneven, as follows
+
+```go
+syntax= "v1"
+
+info(
+key1:value1
+key2:value2
+longkey:longvalue
+)
+
+type Foo {
+  Bar string
+    Baz int
+}
+```
+
+This api file is not read. We can use `goctl api format` to format api files.
+
+## Task Targets
+
+1. familiar with the use of goctl api format
+1. Learn about the function of the goctl api format command
+
+## Preparing
+
+1. <a href="/docs/tasks/installation/goctl" target="_blank">Complete goctl installation</a>
+
+## Format api file
+
+1. Create an api file and copy the following content to the `demo.api` file
+
+    ```go
+    syntax = "v1"
+
+    type User {
+        Id int64 `json:"id"`
+        Name string `json:"name"`
+        Age int `json:"age"`
+        Description string `json:"description"`
+    }
+
+    type Student {
+        Id int64 `json:"id"`
+        No int64 `json:"no"`
+        Name string `json:"name"`
+        Age int `json:"age"`
+        Description string `json:"description"`
+    }
+
+    service User {
+        @handler ping
+        get /ping
+    }
+    ```
+
+1. Create workspace and directory
+
+    ```bash
+    $ mkdir -p ~/workspace/api/format
+    ```
+
+1. Copy the above `demo.api` files to `~/workspace/api/format under directory`
+
+1. Format api file
+
+    ```bash
+    $ cd ~/workspace/api/format
+    $ goctl api format --dir demo.api
+    ```
+
+1. View formatted api files
+
+    ```bash
+    syntax = "v1"
+
+    type User {
+        Id          int64  `json:"id"`
+        Name        string `json:"name"`
+        Age         int    `json:"age"`
+        Description string `json:"description"`
+    }
+
+    type Student {
+        Id          int64  `json:"id"`
+        No          int64  `json:"no"`
+        Name        string `json:"name"`
+        Age         int    `json:"age"`
+        Description string `json:"description"`
+    }
+
+    service User {
+        @handler ping

+## Overview
+
+After completing the <a href="/docs/tasks/installation/goctl" target="_blank">goctl installation</a>, we can create a minimal gRPC service to get an overview of goctl's go-zero gRPC service.
+
+## Task Targets
+
+1. Learn how to create a minimized gRPC service using goctl
+1. Preliminary understanding of the project structure of go-zero
+1. Preliminary method of gRPC local debugging
+
+
+## Preparing
+
+1. <a href="/docs/tasks" target="_blank">Complete golang installation</a>
+1. <a href="/docs/tasks/installation/goctl" target="_blank">Complete goctl installation</a>
+
+## Code Generation
+
+```shell
+# Create workspaces and enter the directory
+$ mkdir -p ~/workspace/rpc && cd ~/workspace/rpc
+# Execute instructions generated demo service
+$ goctl rpc new demo
+Done.
+```
+After executing the instruction, a demo directory will be generated under the current directory that contains a minimized gRPC service. We will check the directory structure of the service.
+
+```shell
+# Enter the demo service directory
+$ cd ~/workspace/rpc/demo
+# view file list
+$ ls
+demo       demo.go    demo.proto democlient etc        go.mod     internal
+# View directory interface
+$ tree

+```
+
+:::note
+API, RPC, Job Directory structure is similar to what the go-zero project structure can look at <a href="/docs/concepts/layout">Project Structure</a>
+:::
+
+## Write simple logic code
+
+After completing the above code generation, we can find `~/workspace/api/demo/internal/logic/demologic.go` files, replace codes at line `29` as follows  :
+
+```go
+return &demo.Response{
+    Pong:"pong",
+}, nil
+```
+
+Then set your profile `~/workspace/rpc/depo/etc/demo.yaml`remove `3` to `7 to` lines of content, then add-on `Mode: dev` to end, making configuration file content：
+
+```yaml
+Name: demo.rpc
+ListenOn: 0.0.0.0:8080
+Mode: dev
+
+```
+
+:::Note
+goctl generates minimized gRPC service by registering information about the current service from ETCD Register, so registration is not required for this demonstration, so the registration center configuration in the configuration file has been deleted.
+:::
+
+## Start service
+
+After writing the above code, we can start the service with the following instructions：
+
+```shell
+# Enter service directory
+$ cd ~/workspace/rpc/demo
+# Organize dependencies
+$ go mod tidy
+# Run go program
+$ go go run demo.go
+```
+
+When you see the following output `Starting rpc server at 0.0.0.0:8080...`indicates that the service has been successfully started, then we come to visit the gRPC service.
