+/*
+ * This example is the smallest code that will create a Matter Device which can be
+ * commissioned and controlled from a Matter Environment APP.
+ * It controls a GPIO that could be attached to a LED for visualization.
+ * Additionally the ESP32 will send debug messages indicating the Matter activity.
+ * Turning DEBUG Level ON may be useful to following Matter Accessory and Controller messages.
+ * 
+ * This example is a simple Matter On/Off Light that can be controlled by a Matter Controller.
+ * It demonstrates how to use On Identify callback when the Identify Cluster is called.
+ * The Matter user APP can be used to request the device to identify itself by blinking the LED.
