+Standalone Ironic
+-----------------
+
+In standalone ironic environments, the placement service is typically not
+available. To prevent Tenks from attempting to communicate with placement, set
+``wait_for_placement`` to ``false``.
+
+It is likely that a standalone ironic environment will not use authentication
+to access the ironic API. In this case, it is possible to set the ironic API
+URL via ``clouds.yaml``. For example:
+
+.. code-block:: yaml
+
+   ---
+   clouds:
+     standalone:
+       auth_type: "none"
+       endpoint: http://localhost:6385
+
+Then set the ``OS_CLOUD`` environment variable to ``standalone``.
