@@ -5,3 +5,22 @@ executing the demo. Executing "demo" without the shell wrapper will not
 provide any tracing support. This ensures the demo binary can be
 distributed on distros without depending on having liblttng-ust.so in
 place. Note: the "demo" program must be compiled with "-ldl".
+
+The simplest command to trace the demo program are:
+lttng create
+lttng enable-event -u -a
+lttng start
+./demo-trace
+lttng destroy
+
+That will create a trace in your $HOME/lttng-traces directory.

+The resulting babeltrace output should look like this:
