automatic start

actually, if I want to play music, I need to use my phone (or my PC) to connect to my Raspberry/Volumio and play start.
Is there a way to the Raspberry starts automaticly with the playlist in memory ?
The aim is to have music even if I have nothing to command the Raspberry.
Thank you

I added the following line:
mpc play
in rc.local file, just before the “exit”
