+Haptic handling under Linux
+========================
+
+In its simplest form, the haptic class just allows control of Haptics from
+userspace. Haptic appears in /sys/class/haptic/. The maximum level of the
+haptic is defined in max_level file.
+
+To use simple. it provides the oneshot mode. Give millisecond time to this
+property. It working at given time with pre-defined level.
+Of course, you can adjust the level by setting level property
+
+# echo ${millisecond} > /sys/class/haptic/<device>/oneshot
+
+# echo ${level} > /sys/class/haptic/<device>/level
+
+Also you can enable/disable by setting enable property
+
+# echo 1 > /sys/class/haptic/<device>/level -> Enable
+# echo 0 > /sys/class/haptic/<device>/level -> Disable

nit-pick: "To make it simple, it provides the one shot mode. Provide
milliseconds time to
this property, and it will be working for the given time with the
pre-defined level."

Please check if my above statement looks better.

"The interface is pretty simple - it provides oneshot mode where user
can specify duration of the effect (in milliseconds) and desired level":

"You can also enable or disable haptics devices by manipulating 'enable'
attribute:"

^^^^^^ enable

^^^^^^
