If you own a 2014 Moto G in the U.S or India (or a 2013 model) go into settings and click the about phone tab to check for system updates if you didn't receive a notification regarding the update on your notification tray.
#Lollipop is rolling out in phases to #MotoG (2nd Gen) in US & #MotoG (1st & 2nd Gen) in India. Look for the notification on your device!
