+Action Plans
+============
+
+An ``Action Plan`` specifies a flow of ``Actions`` that should be executed
+in order to satisfy a given ``Goal``. It also contains an estimated
+``global efficacy`` alongside a set of ``efficacy indicators``.
+
+An ``Action Plan`` is generated by Watcher when an ``Audit`` is successful
+which implies that the ``Strategy`` which was used has found a ``Solution``
+to achieve the ``Goal`` of this ``Audit``.
+
+In the default implementation of Watcher, an action plan is composed of
+a graph of linked ``Actions``. Each action may have parent actions, which
+should be executed prior to child action.

+Actions
+=======
+
+An ``Action`` is what enables Watcher to transform the current state of a
+``Cluster`` after an ``Audit``.
+
+An ``Action`` is an atomic task which changes the current state of a target
+Managed resource of the OpenStack ``Cluster`` such as:
+
+-  Live migration of an instance from one compute node to another compute
+   node with Nova
+-  Changing the power level of a compute node (ACPI level, ...)
+-  Changing the current state of a compute node (enable or disable) with Nova
+
+In most cases, an ``Action`` triggers some concrete commands on an existing
+OpenStack module (Nova, Neutron, Cinder, Ironic, etc.).
+
+An ``Action`` has a life-cycle and its current state may be one of the
+following:
+
+-  **PENDING** : the ``Action`` has not been executed yet by the
+   ``Watcher Applier``.
+-  **ONGOING** : the ``Action`` is currently being processed by the
+   ``Watcher Applier``.
+-  **SUCCEEDED** : the ``Action`` has been executed successfully
+-  **FAILED** : an error occurred while trying to execute the ``Action``.
+-  **DELETED** : the ``Action`` is still stored in the ``Watcher database``
+   but is not returned any more through the Watcher APIs.
+-  **CANCELLED** : the ``Action`` was in **PENDING** or **ONGOING** state and
+   was cancelled by the ``Administrator``
+
+``Actions`` are created by ``Watcher Planner`` as result of Audit's execution.
+``Action`` can't be created, modified or deleted by user.

+There are creating, listing, updating and deleting methods of Watcher Audit

+In the Watcher system, an ``Audit`` is a request for optimizing a ``Cluster``.

+Audit Templates
+===============
+
+There are creating, listing, updating and deleting methods of Watcher Audit
+Template resources which are implemented via the ``/v1/audit_templates``
+resource.
+
+An Audit may be launched several times with the same settings
+(Goal, thresholds, ...). Therefore it makes sense to save those settings in
+some sort of Audit preset object, which is known as an Audit Template.
+
+An Audit Template contains at least the Goal of the Audit.
+

+

+============
+API versions
+============
+
+In order to bring new features to users over time, the Watcher API
+supports versioning. There are two kinds of versions in Watcher.
+
+- ''major versions'', which have dedicated URLs.
+- ''microversions'', which can be requested using the
+  ``OpenStack-API-Version`` header.
+
+.. note:: The maximum microversion depends on release.
+  Please reference:
+  `API Microversion History
+  <https://docs.openstack.org/watcher/latest/contributor/api_microversion_history.html>`__
+  for API microversion history details.
+
+The Version API resource works differently from other API resources as they *do not*
+require authentication.
+
+If Watcher receives a request with unsupported version, it responds with a 406 Not Acceptable,
+along with the -Min- and -Max- headers that it can support.
+
+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.
