 Default behavior
-================
+----------------
+
 If clients of whoas library don't have any whoas configuration, the whoas factory will create
-InMemoryQueue and SequentialHookRunner
+InMemoryQueue that is a simple in memory FIFO with non blocking push and blocking pop operations and
+SequentialHookRunner that has run loop around queue pop and publishes the hook requests.
 
 Library Configuration
-=====================
+---------------------
 
 The clients of whoas library can add "whoas" configuration to build queue and runner of their choice.
 See the example below
 
-whos:
+----
+whoas:
   queueType: "com.github.lookout.whoas.Queue"
   runnerType: "com.github.lookout.whoas.SequentialHookRunner"
