   This example demos the sound effects included in this library.
 
+  This includes the following sound effects:
+    0 (aka "Siren")
+      Intended to sound like a siren, starting at a low frequency, and then
+      increasing rapidly up and then back down. This sound effect does a
+      single "up and down" cycle.
+
+    1 (aka "3 Fast Sirens")
+      Similar to the "Siren" sound effect, only faster and goes three times.
+
+    2 (aka "robot saying 'Yes'")
+      Intended to sound like a robot saying the word "yes".
+      It starts at a low frequency and quickly ramps up to a high frequency, 
+      then stops. This can be interpreted by most to be an affirmative
+      sound to any question you may ask your buzzing robot.      
+
+    3 (aka "robot yelling 'YES!'" - faster)
+      Same as the "Yes" sound effect, only faster.
+      When done more quickly, it can add enthusiasm to the buzzing sound.
+
+    4 (aka "robot saying 'No'")
+      Intended to sound like a robot saying the word "no".
+      It starts at a high frequency and quickly ramps down to a low frequency, 
+      then stops. This can be interpreted by most to be an negative
+      sound to any question you may ask your buzzing robot. 
+
+    5 (aka "robot yelling 'NO!'" - faster)
+      Same as the "No" sound effect, only faster.
+      When done more quickly, it can add enthusiasm to the buzzing sound.
+
+    6 (aka "Laughing Robot")
+      Intended to sound like your robot is laughing at you.
+
+    7 (aka "Laughing Robot Faster")
+      Same as the "Laugh" sound effect, only faster.
+      When done more quickly, it can add enthusiasm to the buzzing sound.
+
+    8 (aka "Crying Robot")
+      Intended to sound like a robot is crying and sad.
+
+    9 (aka "Crying Robot Faster")
+      Same as the "Cry" sound effect, only faster.
+      When done more quickly, it can add enthusiasm to the buzzing sound.
