Arduino M0 Pro and IDE

I have the M0 Pro and version 1.6.6 of the IDE. I click on the Tools -> Boards: and I do not see an entry for the M0 Pro. Is there something else for me to download to use this board?

thanks!

M0 Pro is the card from arduino.org?
This is the Arduino.cc forum.

I think the M0 is a copy of the Zero?

The Zero needs it's board defs installed from the board manager iirc - I don't think it's in by default. But I don't know for sure that the M0 is the same as the Zero.
