 This library makes it easy to connect and listen for NMEA messages from Bluetooth Devices in Windows Store and Windows Phone apps.
 
+Currently supported devices:
+- Generic GPS NMEA
+- Trimble Laser Range Finder
+- TruePulse Laser Range Finder
+
+The API is easily extensible with more NMEA message. Simply create a new class inheriting from "NmeaMessage" and use the NmeaMessageAttribute to tag it with the NMEA Message Token.
+
+Example:
+```
+[NmeaMessageType(Type = "GPRMC")]
+public class Gprmc : NmeaMessage
+{
+	protected override void LoadMessage(string[] message)
+	{
+		//Process message parts
+	}
+}
+```
+
