+If being run as root, fdm requires a user named "fdm" to exist. It will drop
 privileges to this user and its primary group. The user may be added on
 OpenBSD with, for example:
 
-	# useradd -u 999 -s /bin/nologin -d /var/empty -g=uid _fdm
+	# useradd -u 999 -s /bin/nologin -d /var/empty -g=uid fdm
 
 It is not necessary to add a user if fdm is always started by a non-root user.
