+SpRestLib not only provides a simple REST interface, it also delivers next-generation
+async operation handling via [ES6 Promises](http://www.datchley.name/es6-promises/).
 
-SharePoint applications and utilities frequently require many operations be done (e.g.: read from many lists at startup) or steps be performed (e.g.: get an item, then do further operations depending upon the result). The way we've done this until recently is by using callbacks, which are now obsolete.  Promises wait until the previous query completes, which makes async operations easy to chain without any callbacks.
+SharePoint applications frequently perform lots of operations (e.g.: read from many lists at startup)
+or perform sequential steps (e.g.: get an item, then do further operations depending upon the result).
+Until recently, using callbacks was the standard way to handle async completion, but with Promises
+(which all SpRestLib methods return) operations can be easily chained by using `then()`, making your code
+much easier to write and maintain.
