  using a Wiznet Ethernet shield. You can use the Arduino Ethernet shield, or
  the Adafruit Ethernet shield, either one will work, as long as it's got
  a Wiznet Ethernet module on board.
  
+ This example has been updated to use version 2.0 of the Cosm.com API. 
+ To make it work, create a feed with two datastreams, and give them the IDs
+ sensor1 and sensor2. Or change the code below to match your feed.
+ 
  This example uses the String library, which is part of the Arduino core from
  version 0019.
