After you open the app on your Windows Phone, all you have to do is tap "Next" to see if the Windows 10 Mobile update is available to download. If it is, you should see the app display what's below:

3. Download the upgrade
After you tap "Done" on the Upgrade Advisor app, the last step is to go to "Settings" on your Windows Phone, then go to the "Phone Update" selection to check again for the Windows 10 Mobile update. You should be able to start downloading the upgrade if it's ready.
By the way, there are actually two separate downloads. One will update the device to build 10586.107. When that download is installed, check for another update for the final Windows 10 Mobile build 10586.164
