+     "NSQ is a realtime distributed messaging platform designed to operate at
+scale, handling billions of messages per day.
+
+Key features:
+@itemize
+@item support distributed topologies without @acronym{SPOF, Single Point of
+Failure}
+@item scale horizontally (no brokers, seamlessly add more nodes to the
+cluster)
+@item low-latency push based message delivery (performance)
+@item combine load-balanced and multicast style message routing
+@item excel at both streaming (high-throughput) and job oriented
+(low-throughput) workloads
+@item primarily in-memory (beyond a high-water mark messages are transparently
+kept on disk)
+@item runtime discovery service for consumers to find producers (nsqlookupd)
+@item transport layer security (TLS)
+@item data format agnostic
+@item few dependencies (easy to deploy) and a sane, bounded, default
+configuration
+@item simple TCP protocol supporting client libraries in any language
+@item HTTP interface for stats, admin actions, and producers (no client
+library needed to publish)
+@item integrate with @acronym{StatsD, Stats aggregation Daemon} for realtime
+instrumentation
+@item robust cluster administration interface (nsqadmin)
+@end itemize")
