 # This extension is meant to allow connection from remote peers, without actively
 # maintaining this connection ourselves (as it would be the case by declaring the 
 # peer in a ConnectPeer directive).
+#
+# This extension supports configuration reload at runtime. Send
+# signal SIGUSR1 to the process to cause the process to reload its
+# config.
