+Build has been tested on Ubuntu 14.04 LTS on x86_64.
+
+## Prerequisites
+
+You will need the following packages:
+
+* automake
+* autoconf
+* libusb-1.0-0-dev (Package name may vary across distributions)
+
+## Installation
+
+1. Clone the repository

+3. Run configure; make and sudo make install.
 
-* Write a kernel module and export sysfs interfaces to act as a
-driver.
-* Write a userspace program that can configure the kernel module
-and create custom button mappings to keyboard or mouse events.
-* Add interrupt handling and export a /dev/input/jsX interface.
-* Allow userspace programs to register callbacks on MFD button events.
