+	  This option enables support for virtual LED groups that aggregate
+	  multiple monochromatic LEDs with priority-based control. It allows
+	  managing concurrent LED activation requests by ensuring only the
+	  highest-priority LED state is active at any given time.
+
+	  Multiple LEDs can be grouped together and controlled as a single
+	  virtual LED with priority levels and blinking support. This is
+	  useful for systems that need to manage multiple LED indicators
+	  with different priority levels.
+
+	  To compile this driver as a module, choose M here: the module
+	  will be called leds-group-virtualcolor.
