KegNet Install Instructions

This will change once we have a make/make install script.

** Based on Arch Linux ARM (archlinux-hf-2013-11-14) **

http://archlinuxarm.org/platforms/armv6/raspberry-pi

This will not work on Raspbian or any distro other than Arch Linux!

# set the hostname
hostnamectl set-hostname kegnet
