+Example Description
+
+This example describes how to use watchdog api.
+
+Requirement Components: None
+
+In this example, watchdog is setup to 5s timeout.
+Watchdog won't bark if we refresh it before timeout.
+The timer is also reloaded after refresh.
+Otherwise it will restart system in default or call callback function if registered.
