+.Sh NAME
+.Nm smbfs
+.Nd server message block (SMB1/CIFS) file system
+.Sh SYNOPSIS
+To compile this driver into the kernel,
+place the following lines in your
+kernel configuration file:
+.Bd -ragged -offset indent
+.Cd "option NETSMB"
+.Ed
+.Pp
+Alternatively, to load the driver as a
+module at boot time, place the following line in
+.Xr loader.conf 5 :
+.Bd -literal -offset indent
+smbfs_load="YES"
+.Ed
+.Sh DESCRIPTION
+The SMB driver is an implementation of the CIFS (Common Internet Filesystem)
+network protocol.
+.Pp
+.Bf -symbolic
+The
+.Nm
+filesystem driver supports only the obsolete SMBv1 protocol.
+.Nm
+has known bugs and likely has security vulnerabilities.
+.Nm
+and userspace counterparts
+.Xr smbutil 1
+and
+.Xr mount_smbfs 8
+may be removed from a future version of
+.Fx .
+Users are advised to evaluate the
+.Pa filesystems/smbnetfs
+port instead.
