+# -----------------------------------------------------------------------------
+#
+# This script supports running multiple instances of knot.
+# To run additional instances link this script to something like
+# % ln -s knot knot_foo
+# and define additional knot_foo_* variables in one of
+# /etc/rc.conf, /etc/rc.conf.local or /etc/rc.conf.d/knot_foo
+#
+# Below NAME should be substituted with the name of this script. By default
+# it is knot, so read as knot_enable. If you linked the script to
+# knot_foo, then read as knot_foo_enable etc.
+#
+# The following variables are supported (defaults are shown).
+# You can place them in any of
+# /etc/rc.conf, /etc/rc.conf.local or /etc/rc.conf.d/NAME
+#
+# NAME_enable="NO"	# set to YES to enable knot
+#
+# # optional:
+# NAME_config="%%PREFIX%%/etc/knot/NAME.conf"  # (-c)onfig file
+# NAME_diruser="%%USERS%%"   # /var/db/NAME and /var/run/NAME are created if they
+# NAME_dirgroup="%%GROUPS%%"  # don't exist. These don't control the user/group knot
+#                       # runs as, the config file has a setting for that.
+#
+# You also need to set the rundir directive in the server section of the
+# config file to /var/run/NAME (if using a NAME other than the default)
+# and you will want the storage directive(s) declared in the zone section
+# to point to /var/db/NAME overriding the default of /var/db/knot.
+#
+# For further documentation, please see knot.conf(5).
