 The `russound_rio` {% term integration %} allows you to control Russound devices that make use of the RIO protocol.
 
 The platform automatically discovers all enabled zones and sources. Each zone is added as a media player device with the enabled sources available as inputs. Media information is supported if the selected source reports it.
 
-To add a device to your installation, add the following to your {% term "`configuration.yaml`" %} file.
