 CiviCRM Stripe Payment Processor
 --------------------------------
 Version 1.8+ of this extension *must* use Stripe's latest API version (at least 2013-12-03).  
-This is the API setting within your stripe.com account settings (just a button to upgrade).  
+Go to _Account Settings_ -> _API Keys_ tab -> click _Upgrade available_ button.  
 More info on how to change:  https://stripe.com/docs/upgrades#how-can-i-upgrade-my-api  
 
-FIX ME
-------

-It needs to be thoroughly checked for compatibility with the latest version(s) of CiviCRM 4.4+.
