+# Vagrant Cloud Post-Processor
+
+Type: `vagrant-cloud`
+
+The Vagrant Cloud post-processor recieves a Vagrant box from the `vagrant`
+post-processor and pushes it to Vagrant Cloud. [Vagrant Cloud](https://vagrantcloud.com)
+hosts and serves boxes to Vagrant, allowing you to version and distribute
+boxes to an organization in a simple way.
+
+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](http://docs.vagrantup.com/v2/cli/box.html)
+configuration.
+
+## Workflow
+
+It's important to understand the workflow that using this post-processor
+enforces in order to take full advantage of Vagrant and Vagrant Cloud.
+
+The use of this processor assume that you currently distribute, or plan
+to distrubute, boxes via Vagrant Cloud. It also assumes you create Vagrant
+Boxes and deliver them to your team in some fashion.
+
+Here is an example workflow:
+
+1. You use Packer to build a Vagrant Box for the `virtualbox` provider
+2. The `vagrant-cloud` post-processor is configured to point to the box `hashicorp/foobar` on Vagrant Cloud
+via the `box_tag` configuration
+2. The post-processor receives the box from the `vagrant` post-processor
+3. It then creates the configured version, or verifies the existence of it, on Vagrant Cloud
+4. A provider matching the name of the Vagrant provider is then created
+5. The box is uploaded to Vagrant Cloud
+6. The upload is verified
+7. The version is released and available to users of the box
+
+
+## Configuration
+
+The configuration allows you to specify the target box that you have
+access to on Vagrant Cloud, as well as authentication and version information.
+
+### Required:
+
+* `access_token` (string) - Your access token for the Vagrant Cloud API.
+  This can be generated on your [tokens page](https://vagrantcloud.com/account/tokens).
+
+* `box_tag` (string) - The shorthand tag for your box that maps to
+   Vagrant Cloud, i.e `hashicorp/precise64` for `vagrantcloud.com/hashicorp/precise64`
+
+* `version` (string) - The version number, typically incrementing a previous version.
+  The version string is validated based on [Semantic Versioning](http://semver.org/). The string must match
+  a pattern that could be semver, and doesn't validate that the version comes after
+  your previous versions.
+
+
+### Optional:
+
+* `version_description` (string) - Optionally markdown text used as a full-length
+  and in-depth description of the version, typically for denoting changes introduced
+
+* `no_release` (string) - If set to true, does not release the version
+on Vagrant Cloud, making it active. You can manually release the version
+via the API or Web UI. Defaults to false.
+
+* `vagrant_cloud_url` (string) - Override the base URL for Vagrant Cloud. This
+is useful if you're using Vagrant Private Cloud in your own network. Defaults
+to `https://vagrantcloud.com/api/v1`
+
+## Use with Vagrant Post-Processor
+
+You'll need to use the Vagrant post-processor before using this post-processor.
+An example configuration is below. Note the use of the array specifying
+the execution order.
+
+```json
+{
+    "variables": {
+        "version": "",
+        "cloud_token": ""
+    },
+    "builders": [{
+      ...
+    }],
+    "post-processors": [
+      [{
+          "type": "vagrant",
+          "include": ["image.iso"],
+          "vagrantfile_template": "vagrantfile.tpl",
+          "output": "proxycore_{{.Provider}}.box"
+      },
+      {
+          "type": "vagrant-cloud",
+          "box_tag": "hashicorp/precise64",
+          "access_token": "{{user `cloud_token`}}",
+          "version": "{{user `version`}}"
+      }]
+    ]
+}
+
+```
