+Introduction
+=============
+
+This module is intended to try to make the lives of input driver developers
 easier by allowing them to test various serio devices (mainly the various
 touchpads found on laptops) without having to have the physical device in front
 of them. userio accomplishes this by allowing any privileged userspace program
 to directly interact with the kernel's serio driver and control a virtual serio
 port from there.

+Usage overview
+==============
+
+In order to interact with the userio kernel module, one simply opens the
 /dev/userio character device in their applications. Commands are sent to the
 kernel module by writing to the device, and any data received from the serio
 driver is read as-is from the /dev/userio device. All of the structures and
 macros you need to interact with the device are defined in <linux/userio.h> and
 <linux/serio.h>.

 would set the port type to be a normal PS/2 port.
