+# OpenStack Builder
+
+Type: `openstack`
+
+The `openstack` builder is able to create new images for use with
+[OpenStack](http://www.openstack.org). The builder takes a source
+image, runs any provisioning necessary on the image after launching it,
+then creates a new reusable image. This reusable image can then be
+used as the foundation of new servers that are launched within OpenStack.
+The builder will create temporary keypairs that provide temporary access to
+the server while the image is being created. This simplifies configuration
+quite a bit.
+
+The builder does _not_ manage images. Once it creates an image, it is up to
+you to use it or delete it.
+
+## Configuration Reference
+
+There are many configuration options available for the builder. They are
+segmented below into two categories: required and optional parameters. Within
+each category, the available configuration keys are alphabetized.
+
+Required:
+
+* `flavor` (string) - The ID or full URL for the desired flavor for the
+  server to be created.
+
+* `image_name` (string) - The name of the resulting image.
+
+* `password` (string) - The password used to connect to the OpenStack service.
+  If not specified, Packer will attempt to read this from the
+  `SDK_PASSWORD` environment variable.
+
+* `provider` (string) - The provider used to connect to the OpenStack service.
+  If not specified, Packer will attempt to read this from the
+  `SDK_PROVIDER` environment variable.
+
+* `source_image` (string) - The ID or full URL to the base image to use.
+  This is the image that will be used to launch a new server and provision it.
+
+* `username` (string) - The username used to connect to the OpenStack service.
+  If not specified, Packer will attempt to read this from the
+  `SDK_USERNAME` environment variable.
+
+Optional:
+
+* `ssh_port` (int) - The port that SSH will be available on. Defaults to port
+  22.
+
+* `ssh_timeout` (string) - The time to wait for SSH to become available
+  before timing out. The format of this value is a duration such as "5s"
+  or "5m". The default SSH timeout is "1m".
+
+* `ssh_username` (string) - The username to use in order to communicate
+  over SSH to the running droplet. The default is "root".
+
+## Basic Example
+
+Here is a basic example. This is a working example to build a
+Ubuntu 12.04 LTS (Precise Pangolin) on Rackspace OpenStack cloud offering.
