Motorola is rolling out the Android 5.0.1 Lollipop update for the 1st and 2nd Generation Moto G in India.
As usual, the update is rolling out in phases, so not everyone will get it at the same time but your phone should show you a notification as soon as the update is available for download. Alternatively, you can check if the update OTA package is available by going to Settings > About phone > System updates.
