+.Sh NAME
+.Nm chromebook_platform
+.Nd support driver for hardware on various Chromebook models
+.Sh SYNOPSIS
+To compile this driver into the kernel, place the following lines into
+the kernel configuration file:
+.Bd -ragged -offset indent
+.Cd "device chromebook_platform"
+.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
+chromebook_platform_load="YES"
+.Ed
+.Sh DESCRIPTION
+The
+.Nm
+driver provides automatic configuration for devices that cannot be enumerated
+or safely probed.
+In particular, I2C peripherals are different from model to model.
+.Nm
+has a model-specific information about the I2C peripherals, their drivers,
+their bus attachments and slave addresses.
+.Pp
+Note that
+.Nm
+does not load driver modules for the peripherals.
+Those have to be compiled into the kernel or loaded separately.
