 Core Tests
 
 This module contains all the tests that pertain to the usage of the Tutorius
-Core. This means that the the Finite State Machine, States and all the 
+Core. This means that the Event Filters, the Finite State Machine and all the 
 related elements and interfaces are tested here.
 
 Usage of actions and event filters is tested, but not the concrete actions
