+The Vagrant Cloud post-processor enables the upload of Vagrant boxes to Vagrant
+Cloud. Currently, the Vagrant Cloud post-processor will accept and upload boxes

+[Vagrant](/docs/builders/vagrant.html) builder.

 You'll need to be familiar with Vagrant Cloud, have an upgraded account to
 enable box hosting, and be distributing your box via the [shorthand
 name](https://docs.vagrantup.com/v2/cli/box.html) configuration.
