 Now, in your monkey file, you could use it like below:
 
 ```swift
-    gfmt.Printf("Hello %s!\n", "go function");
+gfmt.Printf("Hello %s!\n", "go function");
 
-    //Note Here: we use 'io_ioutil', not 'io/ioutil'.
-    let files, err = io_ioutil.ReadDir(".")
-    if err != nil {
-        gfmt.Println(err)
-    }
+//Note Here: we use 'io_ioutil', not 'io/ioutil'.
+let files, err = io_ioutil.ReadDir(".")
+if err != nil {
+    gfmt.Println(err)
+}
 ```

 接下来, 在你的Monkey文件中，像下面这样使用导入的方法:
 
 ```swift
-    gfmt.Printf("Hello %s!\n", "go function");
+gfmt.Printf("Hello %s!\n", "go function");
 
-    //注意: 这里需要使用'io_ioutil', 而不是'io/ioutil'。
-    let files, err = io_ioutil.ReadDir(".")
-    if err != nil {
-        gfmt.Println(err)
-    }
+//注意: 这里需要使用'io_ioutil', 而不是'io/ioutil'。
+let files, err = io_ioutil.ReadDir(".")
+if err != nil {
+    gfmt.Println(err)
+}
 ```
