 ```
 
-And then directly import it in your app:
+You can also use the global `vue-devtools` to start the app, but you might want to check if the local version matches the global one in this scenario to avoid any incompatibilities.
+
+Then import it directly in your app:
 ```js
 import devtools from '@vue/devtools'
+// import Vue from 'vue'
+```
+> Make sure you import devtools before Vue, otherwise it might not work as expected.
 
+And connect to host:
+```js
 if (process.env.NODE_ENV === 'development') {
-  devtools.connect()
+  devtools.connect(/* host */)
 }
 ```
 
+**host** - is an optional argument that tells your application where devtools middleware server is running, if you debug you app on your computer you don't have to set this (the default is `http://localhost`), but if you want to debug your app on mobile devices, you might want to pass your local IP (e.g. `192.168.1.12`).
