+*****************************************************************************
+** ChibiOS/RT port for ATxmega128a4u.                                      **
+*****************************************************************************
+
+** TARGET **
+
+The demo runs on the mattair Tech MT-DB-X4 board.
+
+** The Demo **
+
+The demo demonstrate how to use Crypto driver to encrypt and decrypt data.
+
+** Build Procedure **
+
+The demo was built using the GCC AVR toolchain. It should build with WinAVR too!
+
+** Programming procedure **
+
+The board can be flash by using the Makefile and the DFU Programmer tools.
+See the make file for more details.
