+// 				MyMQTT Gateway 0.1b
+//
+// Created by Daniel Wiegert <daniel.wiegert@gmail.com>
+// Based on Mysensors Ethernet Gateway by Henrik Ekblad <henrik.ekblad@gmail.com>
+// http://www.mysensors.org
+//
+// Requires MySensors lib 1.4b
+// 
+// Don't forget to look at the definitions in MyMQTT.h! 
+// Don't forget to configure Radio pins, IP and MAC-address!
+// 
+// Address-layout is : [MQTT_BROKER_PREFIX]/[NodeID]/[SensorID]/Light
+// NodeID and SensorID is Decimal number.
+// Last segment is translation of the sensor type, look inside MyMQTT.cpp for 
+// the definitions. User can change this to their needs.
+//
+// Features:
+// Supports automatic nodeID delegation
+// Recieve sketchname and version Example: (openhab item)
+//String sketch20 "Node 20 Sketch name [%s]"			(sketch,name,a)	{mqtt="<[mysensor:MyMQTT/20/255/Sketch_name:state:default]"}
+//String sketch21 "Node 21 Sketch name [%s]"			(sketch,name,a)	{mqtt="<[mysensor:MyMQTT/21/255/Sketch_name:state:default]"}
+// ...
+//
+// Todo:
+// DOCUMENTATION...
+// Special commands : clear or set EEPROM Values
+// Special commands : Reboot
+// ...
