  * ESP8266 WiFi controller for Kerbal Space Program 
  * 
  * Uses web sockets to connect to Telemachus on the host
+ * 
+ * If it is not on your WiFi, it will create its own.  Connect to it,
+ * and set your WiFi details.  Then it will join your WiFi network.
+ * 
+ * Connect to the ESP8266 using your browser to specify the target IP.
+ * It takes 5-10 seconds from power on to connection.
+ * 
+ * This example uses a button between ground and pin 5 which will stage, 
+ * and a potentiometer on A0 which controls the throttle.
+ * 
+ * The blue LED (Pin 2) will be on when connected to Telemachus.
+ * Enable DEBUG to get status messages over the serial connection
