 #### 7. Run a command until an event is set
-If the argument `stop_event` is set when calling `run()`, the controller
-ignores `timeout` and stops only when the given event is triggered instead.
-This is especially useful when using threads.
+If the argument `stop_event` (a `threading.Event` object) is set when
+calling `run()`, the controller ignores `timeout` and stops when the given
+event is triggered instead. This is especially useful when using threads.
 
 The example below starts two threads with an event attached to each one:
-one is pinging localhost, the other sleeps for 10s. When the sleeping threads
-has finished, the events are triggered to also stop the pinging thread.
