-This documentation is generated by the Sphinx toolkit and lives in the source
-tree. Additional draft and project documentation on Cinder and other components
-of OpenStack can be found on the `OpenStack wiki`_. Cloud administrators, refer
-to `docs.openstack.org`_.
+For end users
+-------------
 
-.. _`OpenStack wiki`: https://wiki.openstack.org/wiki/Main_Page
-.. _`docs.openstack.org`: https://docs.openstack.org
+As an end user of Cinder, you'll use Cinder to create and manage volumes using
+the Horizon user interface, command line tools such as the
+`python-cinderclient <https://docs.openstack.org/python-cinderclient/latest/>`_,
+or by directly using the
+`REST API <https://developer.openstack.org/api-ref/block-storage/>`_.
 
+Tools for using Cinder
+~~~~~~~~~~~~~~~~~~~~~~
 
-Installation Guide
-~~~~~~~~~~~~~~~~~~
+* `Horizon <https://docs.openstack.org/horizon/latest/user/manage-volumes.html>`_:
+  The official web UI for the OpenStack Project.
+* `OpenStack Client <https://docs.openstack.org/python-openstackclient/latest/>`_:
+  The official CLI for OpenStack Projects. You should use this as your CLI for
+  most things, it includes not just nova commands but also commands for most of
+  the projects in OpenStack.
+* `Cinder Client <https://docs.openstack.org/python-cinderclient/latest/user/shell.html>`_:
+  The **openstack** CLI is recommended, but there are some advanced features
+  and administrative commands that are not yet available there. For CLI access
+  to these commands, the **cinder** CLI can be used instead.
+
+Using the Cinder API
+~~~~~~~~~~~~~~~~~~~~
+
+All features of Cinder are exposed via a REST API that can be used to build
+more complicated logic or automation with Cinder. This can be consumed directly
+or via various SDKs. The following resources can help you get started consuming
+the API directly.
+
+* `Cinder API <https://developer.openstack.org/api-ref/block-storage/>`_
+* :doc:`Cinder microversion history </contributor/api_microversion_history>`
+
+For operators
+-------------
+
+This section has details for deploying and maintaining Cinder services.
+
+Installing Cinder
+~~~~~~~~~~~~~~~~~
+
+Cinder can be configured standalone using the configuration setting
+``auth_strategy = noauth``, but in most cases you will want to at least have
+the `Keystone <https://docs.openstack.org/keystone/latest/install/>`_ Identity
+service and other
+`OpenStack services <https://docs.openstack.org/latest/install/>`_ installed.
