 This will create a 3 node devstack (controller + two computes), where Dragonflow is used as
 the Open vSwitch backend.
 
 Vagrant allows to configure the provider on which the virtual machines are
 created. Virtualbox is the default provider used to launch the VM's on a

 Quick Start
 -----------
 
-1. Install Virtualbox (https://www.virtualbox.org/wiki/Downloads) and Vagrant
-   (https://www.vagrantup.com/downloads.html).
+1. Install a Hypervisor if not already installed
 
-2. Configure
