Installing Cuckoo Sandbox is fairly straightforward and can be achieved 
through the following few instructions:

* Install Ubuntu 14.04.2 LTS on a machine
* Download the setup.sh script
    wget https://raw.githubusercontent.com/cuckoobox/cuckoo/master/utils/setup.sh
* Make it executable
    chmod +x setup.sh
* Copy a Windows XP Installer ISO on to the machine with a working serial key
* sudo ./setup.sh -i winxp.iso -s SERIALKEYHERE
* If the script fails for some reason, just run it again.
* Cuckoo Sandbox has been installed, you're now good to go.

Note: No warranties are included in this setup script. It may or may not work
for you. Also, if you reboot the system, then you might have to reproduce some
steps for now.
