+  UploadToDropbox
+  
+  Demonstrates uploading a file to Dropbox using the Temboo Arduino Yun SDK.
+
+  Check out the latest Arduino & Temboo examples and support docs at http://www.temboo.com/arduino
+
+  A Temboo account and application key are necessary to run all Temboo examples. 
+  If you don't already have one, you can register for a free Temboo account at 
+  http://www.temboo.com
+
+  You'll also need a valid Dropbox account, and OAuth credentials for Dropbox. To
+  obtain OAuth credentials for Dropbox, you'll need to register a Dropbox app at 
+  https://www.dropbox.com/developers/apps and then follow the instructions at 
+  https://www.temboo.com/library/Library/Dropbox/OAuth/ to run the Initialize and Finalize
+  OAuth Choreos to complete the OAuth handshake and retrieve your Access Token information.
+
+  This example assumes basic familiarity with Arduino sketches, and that your Yun is connected
+  to the Internet.
+
+  Looking for another API? We've got over 100 in our Library!
+  
+  This example code is in the public domain.

+  IMPORTANT NOTE About TembooAccount.h:
+
+  TembooAccount.h is not included with this example because it contains your account information.
+  You need to create it for your own version of this application.  To do so, make
+  a new tab in Arduino, call it TembooAccount.h, and include the following variables and constants:
+
+  #define TEMBOO_ACCOUNT "matthew-yun"  // your Temboo account name 
+  #define TEMBOO_APP_KEY_NAME "someKey"  // your Temboo app key name
+  #define TEMBOO_APP_KEY  "fveIrkjAVIkuNUUPE6df"  // 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
+
+  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.
