I feel silly asking l2d icon

I have had a user asking how to get the l2d icon on his new phone. I have it on mine and forgot how to get it back to a new phone. Am I even sillier and not found the write up on how to do it also? please help

Ok its easy and yes I answered my own question.
So all you do is go to this website via your phone in google chrome and the 3 buttons on top right press them and select add to home screen. confirm it and its done.
