+The Raspberry Pi will listen on TCP port 8011, and wait for connection.
+
+Then, on the remote computer, execute:
+
+    arecord -fS16_LE -r48000 -c1 - | nc raspberrypi.local 8011
+
+You should replace `raspberrypi.local` with the IP address of the Raspberry Pi (unless avahi config is the default).
