14. Enter vagrant
    ● Configuration: Vagrantfile
    ● Boxes: Exported Virtual Machines + metadata
    ● Providers: VirtualBox
    ● Synced folders: Folders from the host which are
    dublicated inside the VM
    ● Provisioners: Shell / ansible / Chef / Puppet
    ● Plugins: Way to extend Vagrant with additional
    Providers, Provisioners and other stuff

    config.vm.hostname = "drupal"
    config.vm.box = "precise64"
    config.vm.box_url = "http://files.vagrantup.com/precise64.box"
    config.vm.synced_folder "../project", "/var/www/project"
    config.vm.provision shell, inline: "sudo apt-get update"
