Google Home doesn’ t sport a screen, so in order to setup the device, you need Google Home app installed on your smartphone / tablet. �
If you are using an Android device, then you can get the app from Google Play Store, and if you are using an iOS device, then the app can be obtained from Apple App Store.
Plug in the adapter that comes along with Google Home. One end will be connected to the wall outlet and another end will be plugged into the Google Home device. As you do it, Google Home will start the booting process where you will see multi-coloured lights.
