#
# Installation steps:
#
# - Install lates Virtualbox and its guest extensions pack
#   https://www.virtualbox.org/wiki/Downloads
# - Install Vagrant
#   https://www.vagrantup.com/
# - cd /where/you/want
# - cp Vagrantfile .
# - vagrant up
#   (you will be prompted for your sudo password when vagrant tunes nfs config)
# - vagrant ssh
#
# Quick check the installation in a shell of the guest Ubuntu VM:
#
# - docker run hello-world
# -------------------------------
