Playing Roon on my phone

Hi this is my first post. Very new to Roon. Running it on my Acer laptop and Ayre QB9 DAC. Things are fine I use my phone and my tablet as remote controls, but I would like to use both or either as a play zone or player so I can listen while in other rooms in the house. How do I make my phone/tablet discoverable by Roon?
Thanks for your help

If they are already being used as a control they are already discovered by Roon. You just need to enable audio snd switch to their zone and play music to it.
