+	Usage: $PROGRAM [ up | down | save ] [ CONFIG_FILE | INTERFACE ]
+
+	  CONFIG_FILE is a configuration file, whose filename is the interface name
+	  followed by \`.conf'. Otherwise, INTERFACE is an interface name, with
+	  configuration found at /etc/wireguard/INTERFACE.conf. It is to be readable
+	  by wg(8)'s \`setconf' sub-command, with the exception of the following additions
+	  to the [Interface] section, which are handled by $PROGRAM:
+
+	  - Address: may be specified one or more times and contains one or more
+	    IP addresses (with an optional CIDR mask) to be set for the interface.
+	  - DNS: an optional DNS server to use while the device is up.
+	  - MTU: an optional MTU for the interface; if unspecified, auto-calculated.
+	  - Table: an optional routing table to which routes will be added; if
+	    unspecified or \`auto', the default table is used. If \`off', no routes
+	    are added.
+	  - PreUp, PostUp, PreDown, PostDown: script snippets which will be executed
+	    by bash(1) at the corresponding phases of the link, most commonly used
+	    to configure DNS. The string \`%i' is expanded to INTERFACE.
+	  - SaveConfig: if set to \`true', the configuration is saved from the current
+	    state of the interface upon shutdown.
+
+	See wg-quick(8) for more info and examples.
