How to add a usb hard drive w music to volumio

Complete noob here. I have connected a usb hdd to my raspberry pi and was hoping to have volumio find and serve the music on that hard disk, but can’t find how to do that.
Any pointers would be much appreciated.

Assuming your USB drive is getting adequate power, either from the R Pi USB port, or via a mains adapter, and has a compatible file system:

  • Settings
  • Sources
    You should already see the USB drive there.
