 ## Introduction
 
-**ndnping** and **ndnpingserver** are reachability testing tools for
-[Named Data Networking](http://named-data.net). They test the reachability between two nodes. The
-client sends an Interest intended for a node running **ndnpingserver**. The ping server then sends
-Data in response. The client then calculates the roundtrip time for the Interest-Data exchange, or
-marks it as a timeout if the Data is not received within the timeout period.

-## ndnping Protocol
+## NDN ping protocol
 
 This section briefly describes ndnping's protocol, in order to allow alternate implementations
 to be compatible with this implementation.
+
 The current protocol version is **ndnping protocol version 1**.
-This version number will be incremented in case there's an incompatible change.
+This version number will be incremented whenever there is an incompatible change.
