+Title: Synchronisation
+
+Description:
+
+A simple Hello World example using the microkernel.
+
+--------------------------------------------------------------------------------
+
+Building and Running Project:
+
+This microkernel project outputs to the console. It can be built and executed
+on QEMU as follows:
+
+ make qemu
+
+--------------------------------------------------------------------------------
+
+Troubleshooting:
+
+Problems caused by out-dated project information can be addressed by
+issuing one of the following commands then rebuilding the project:
+
+ make clean # discard results of previous builds
+ # but keep existing configuration info
+or
+ make pristine # discard results of previous builds
+ # and restore pre-defined configuration info
+
+--------------------------------------------------------------------------------
+
+Sample Output:
+
+Hello World!
