+.Sh NAME
+.Nm stg
+.Nd driver for Future Domain based SCSI controllers
+.Sh SYNOPSIS
+To compile this driver into the kernel,
+place the following lines in your
+kernel configuration file:
+.Bd -ragged -offset indent
+.Cd "device scbus"
+.Cd "device stg"
+.Pp
+For one or more ISA cards:
+.Cd "device isa"
+.Pp
+In
+.Pa /boot/device.hints :
+.Cd hint.stg.0.at="isa"
+.Pp
+For one or more PCI cards:
