+# Async Functions
+
+*Async Functions* are functions that can suspend their execution to wait for the completion of an 
+asynchronous operation. This allows complex algorithms that require asynchronous control flow to
+be written sequentially.
+
+This sample uses *Async Functions* to query the GitHub API to view information about recent pull 
+requests.
+
+This sample requires a minimum of NodeJS v4.0.0. 
+
