+
+#### Introduction
+
+HugeGraph client SDK tool based on Go language
+
+#### Software Architecture
+
+Software Architecture Description
+
+#### Installation Tutorial
+
+```Shell
+
+Go get github. com/go huggraph
+
+```
+
+#### Implement API
+
+| API     | illustrate              |
+|---------|-------------------------|
+| schema  | Obtain the model schema |
+| version | Get version information |
+
+#### Instructions for use
+
+##### 1. Initialize the client
+
+```Go
+package main
+
+import "github.com/apache/incubator-hugegraph-toolchain/hugegraph-client-go"
+import "github.com/apache/incubator-hugegraph-toolchain/hugegraph-client-go/hgtransport"
+
+func main() {
+
+    clinet, err := hugegraph.NewCommonClient(hugegraph.Config{
+        Host:     "127.0.0.1",
+        Port:     8080,
+        Graph:    "hugegraph",
+        Username: "",
+        Password: "",
+        Logger: &hgtransport.ColorLogger{
+            Output:             os.Stdout,
+            EnableRequestBody:  true,
+            EnableResponseBody: true,
+        },
+    })
+
+    if err != nil {
+        log.Fatalf("Error creating the client: %s\n", err)
+    }
+}
+```
+
+##### 2. Obtain the hugegraph version
+
+-1. Use the SDK to obtain version information
+
+```Go
+package main
+
+import (
+    "fmt"
+    "log"
+)
+
+func getVersion() {
+
+    client := initClient()
+    res, err := client.Version()
+    if err != nil {
+        log.Fatalf("Error getting the response: %s\n", err)
+    }
+    defer res.Body.Close()
+
+    fmt.Println(res.Versions)
+    fmt.Println(res.Versions.Version)
+}
+```
+
+-2. Result Set Response Body
+
+```Go
+package main
+
+type VersionResponse struct {
+    Versions struct {
+        Version string `json:"version"` // hugegraph version
+        Core    string `json:"core"`    // hugegraph core version
+        Gremlin string `json:"gremlin"` // hugegraph gremlin version
+        API     string `json:"api"`     // hugegraph api version
+    } ` json: 'versions'`
+}
+```
