+module: rax_identity
+short_description: Load Rackspace Cloud Identity
+description:
+     - Verifies Rackspace Cloud credentials and returns identity information
+version_added: "1.5"
+options:
+  api_key:
+    description:
+      - Rackspace API key (overrides C(credentials))
+  credentials:
+    description:
+      - File to find the Rackspace credentials in (ignored if C(api_key) and
+        C(username) are provided)
+    default: null
+    aliases: ['creds_file']
+  region:
+    description:
+      - Region to authenticate against
+    default: DFW
+  state:
+    description:
+      - Indicate desired state of the resource
+    choices: ['present', 'absent']
+    default: present
+  username:
+    description:
+      - Rackspace username (overrides C(credentials))
+requirements: [ "pyrax" ]
+author: Christopher H. Laco, Matt Martz
+notes:
+  - The following environment variables can be used, C(RAX_USERNAME),
+    C(RAX_API_KEY), C(RAX_CREDS_FILE), C(RAX_CREDENTIALS), C(RAX_REGION).
+  - C(RAX_CREDENTIALS) and C(RAX_CREDS_FILE) points to a credentials file
+    appropriate for pyrax. See U(https://github.com/rackspace/pyrax/blob/master/docs/getting_started.md#authenticating)
+  - C(RAX_USERNAME) and C(RAX_API_KEY) obviate the use of a credentials file
+  - C(RAX_REGION) defines a Rackspace Public Cloud region (DFW, ORD, LON, ...)
