Installing Archey
This is very optional, however I like it. Archey will show you some nice information on login.
To install it, simply run:
apt-get install lsb-release scrot
cd /tmp
wget https://github.com/downloads/djmelik/archey/archey-0.2.8.deb
dpkg -i archey-0.2.8.deb
rm archey-0.2.8.deb
vi /etc/bash.bashrc
at the end add: archey
