+============
+API versions
+============
+
+Concepts
+========
+
+In order to bring new features to users over time, the Ironic
+Inspector API supports versioning. There are two kinds of versions:
+
+- ``major versions``, which have dedicated urls.
+- ``microversions``, which can be requested through the use of the
+  ``X-OpenStack-Ironic-Inspector-API-Version`` header.
+
+The Version APIs work differently from other APIs as they *do not* require authentication.
+
+All API requests support the ``X-OpenStack-Ironic-Inspector-API-Version`` header.
+This header SHOULD be supplied with every request; in the absence of this header,
+server will default to current supported version in all responses.
+
+List API versions
+=================
+
+.. rest_method::  GET /
+
+This fetches all the information about all known major API versions in the
+deployment. Links to more specific information will be provided for each major
+API version, as well as information about supported min and max microversions.
