 Overview
 --------
-These code files provide drivers to interface with Analog Devices family of
-impedance-converters listed above and communicate with any compatable evaluation board.
-This code was developed and tested on SDP-K1 controller board 
-https://os.mbed.com/platforms/SDP_K1/ and used the Digilent PMOD 1A board for testing.
-
+These code files provide the console application and device libraries to 
+interface with AD5933/AD5934 EVAL boards. This code was developed and tested on SDP-K1 
+controller board: https://os.mbed.com/platforms/SDP_K1/ and and used the Digilent PMOD 1A board for testing.
