+# Which configuration file to load instead of unrealircd.conf. If you
+# want to run multiple instances of unrealircd, you must edit
+# files::pidfile to match UNREALIRCD_PIDFILE. You should also ensure
+# that files::tunefile is different for each unrealircd instance. See
+# https://www.unrealircd.org/docs/Configuration#Files_block
+#
+# To support multiple instances of unrealircd, you may create symlinks
+# in /etc/init.d pointing to /etc/init.d/unrealircd. It is recommended
+# that the scheme unrealircd.${instance_name} be used. For each
+# instance, you may make a copy of this file with the appropriate name
+# to override default options specific to that instance.
