+# Import package from remote modules
+An import path can describe how to obtain the package source code using a revision control system such as Git or Mercurial. The go tool uses this property to automatically fetch packages from remote repositories. 
+
+```bash
+cp -r 2-importpackage 3-importremote
+# change importpackage to importremote
+nano go.mod
+nano importpackage/reverse.go
+# update modules in hello.go
+nano hello.go
+>   package main

+>   import (
+>   	"fmt"
+>   
+>   	"example/user/importremote/importpackage"

+>   	fmt.Println(cmp.Diff("Hello World", "Hello Go"))
+>   }
+# get all requirements and download modules
+go mod tidy
+# run code
+go run hello.go
+```
