 **Grasshopper** is a UDP packet forwarder that listens for incoming packets and forwards them to a configured destination. It optionally supports cryptography for both incoming and outgoing packets, using different keys and methods.
 
 ## Architecture
-Grasshopper functions as a chained relay system. For example:
+Grasshopper functions as a chained relay system. Take a chained DNS query For example:
