+.Sh NAME
+.Nm acpi_wmi
+.Nd "ACPI to WMI mapping driver"
+.Sh SYNOPSIS
+To compile this driver into the kernel,
+place the following line in your
+kernel configuration file:
+.Bd -ragged -offset indent
+.Cd "device acpi_wmi"
+.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
+acpi_wmi_load="YES"
+.Ed
+.Sh DESCRIPTION
+The
+.Nm
+driver provides an interface for vendor specific WMI implementations
+(e.g. HP and Acer laptops). It creates /dev/wmistat, which can be read to get
+information about GUIDs found in the system.
+.Sh FILES
