Introduction
The Impero Client Application and Impero Client Extension for Chromebook allow you to integrate your Chromebook devices with
your Impero Education Pro network. There are two applications that you need to download from the Chrome Web Store in order
to join your Chromebook device to your network . You are required to be running Impero version 4.2.20 or later in order to view
Chromebook screens from your Impero Console.
Once installed on your device, the applications can be configured to connect to your Impero Server and become viewable from your
Impero Console.
