+description: |
+  Bindings for multi color LEDs show how to describe current outputs of
+  either integrated multi-color LED elements (like RGB, RGBW, RGBWA-UV
+  etc.) or standalone LEDs, to achieve logically grouped multi-color LED
+  modules. This is achieved by adding multi-led nodes layer to the
+  monochrome LED bindings.
+  The nodes and properties defined in this document are unique to the multicolor
+  LED class.  Common LED nodes and properties are inherited from the common.txt
+  within this documentation directory.
