+-- Demo 6 ------------------------------------------------------------------------
+
+This demo demonstrates how to use basic interrupts such as the [ON] key
+
+-- Compiling ----------------------------------------------------------------------
+
+To compile this demo project, simply run `make` within a shell in
+this directory. You can change the name or description for the demo like this:
+    make TARGET=myprog DESCRIPTION="Some description here"
+
+If you wish to easily delete all the created files outputted by make, type:
+    make clean
+
+----------------------------------------------------------------------------------
+
+This demo is a part of the C SDK Toolcahin for use on the CE.
