+=== Define Timers
+Transition can also happen based on timed events. Spring Statemachine
+support two types of timers, ones which fires continously on a
+background and ones which fires once with a delay when state is
+entered.
+
+Add new `TimeEvent` child to _Model Explorer_, modify _When_ as
+expression defined as _LiteralInteger_. Value of it is then timer as

 === Define Actions
 State entry and exit actions can be associated by using a behaviour,
