Before you start the upgrade process, you need to make sure that the battery of your device is at least at 85 % and you are connected to a stable WiFi connection. After you done this, go to Settings > About phone > Software update. By doing this, the latest upgrades available for your Android version will be automatically downloaded and installed.
