 It works with a Virtualbox VM, driven by Vagrant.
 
 To install Virtualbox and Vagrant (version 1.8 is not available on Debian repositories yet) :
 
 ```
-$ apt install virtualbox
-$ curl -O https://releases.hashicorp.com/vagrant/1.8.5/vagrant_1.8.5_x86_64.deb /tmp/
-$ dpkg -i /tmp /vagrant_1.8.5_x86_64.deb

+# dpkg -i /tmp /vagrant_1.8.5_x86_64.deb
 ```
 
 To bring the VM up and run the playbook, simply run `$ vagrant up` from the root of this repository.
