+  The gateway owner's contact information.
+
+##Optional global variables
+* GW_GPS optional - default False
+  * If True, use the hardware GPS. 
+  * If False, 
+    use either fake gps if a location was configured in the TTN console, 
+    otherwise try using fake gps with the reference location as set via environment variables, 
+    otherwise don't send coordinates. 
+* GW_GPS_PORT optional - default /dev/ttyAMA0
+  The UART to which the hardware GPS is connected to.
+* GW_REF_LATITUDE optional - default 0
+  The latitude to use for fake gps if the coordinates are not set in the TTN console.
+* GW_REF_LONGITUDE optional - default 0
+  The longitude to use for fake gps if the coordinates are not set in the TTN console.
+* GW_REF_ALTITUDE optional - default 0
+  The altitude to use for fake gps if the coordinates are not set in the TTN console.
+
+##Server variables
+All server variables are optional, but when a server is enabled, it is recommended to set all variables to configure it completely.
+* SERVER_TTN optional - default True
+  Should the gateway connect to the TTN backend
+  
+* SERVER_1_ENABLED optional - default false
+* SERVER_1_TYPE - default "semtech"
