   IMPORTANT NOTE: TembooAccount.h:
 
-  TembooAccount.h is a file referenced by this sketch that contains your Temboo account information. 
-  You need to create this file. To do so, make a new tab in Arduino, call it TembooAccount.h, and 
-  include the following variables and constants:
+  TembooAccount.h is a file referenced by this sketch that contains your Temboo account information.
+  You'll need to edit the placeholder version of TembooAccount.h included with this example sketch,
+  by inserting your own Temboo account name and app key information. The contents of the file should
+  look like:
 
   #define TEMBOO_ACCOUNT "myTembooAccountName"  // your Temboo account name 
   #define TEMBOO_APP_KEY_NAME "myFirstApp"  // your Temboo app key name
   #define TEMBOO_APP_KEY  "xxx-xxx-xxx-xx-xxx"  // your Temboo app key
 
-  The same TembooAccount.h file settings can be used for all Temboo SDK sketches.
-
   You can find your Temboo App Key information on the Temboo website, 
   under My Account > Application Keys
-  
+
+  The same TembooAccount.h file settings can be used for all Temboo SDK sketches.
+
   Keeping your account information in a separate file means you can save it once, 
   then just distribute the main .ino file without worrying that you forgot to delete your credentials.
