+~~This library is still a work in progress, so api breaking changes may happen
+in the future.~~  
+This library is usable. Try testing it out using the `NetworkTest` binary which
+is built when Debug builds are enabled (the default) with CMake.
+
+    $ ./NetworkTest
+    [-c | -s] - client or server (default server)
+    -ll <addr> - listen addr
+    -lp <port> - listen port
+    -cl <addr> - connection addr (client only)
+    -clh <hostname> - connection hostname (client only)
+    -cp <port> - connection port (client only)
+    -t <tick_count>
+    -n - do not add payload to packets
+    -l (silent|error|warning|info|verbose|debug) - log level, default debug
+    -e - enable receiving events
+    -ls - enable libsodium
+    -ck <pubkey_file> - add pubkey to whitelist
+    -sk <pubkey> <seckey> - start with pub/sec key pair
+    -p <"fallback" or "strict"> - set auth policy
+    --hostname <hostname> - dont run test, just lookup hostname
+
+A typical test can be done with the following parameters:
+
+Server:
+
+    ./NetworkTest -s -ll ::1 -lp 9000 -t 50 -e
+
+Client:
+
+    ./NetworkTest -c -ll ::1 -lp 9001 -cl ::1 -cp 9000 -t 40 -e
+
+`NetworkTest` gracefully shuts down on SIGINT (Ctrl-C).
+
+The source of `NetworkTest` can be found in `src/test/UDPC_NetworkTest.c`.
