+FAQs
+----
+
+#. How is the nova-status upgrade script packaged and deployed?
+
+   There is a ``console_scripts`` entry for ``nova-status`` in the
+   ``setup.cfg`` file.
+
+#. Why are there multiple parts to the command structure, i.e. "upgrade" and
+   "check"?
+
+   This is an artifact of how the ``nova-manage`` command is structured which
+   has categories of sub-commands, like ``nova-manage db`` is a sub-category
+   made up of other sub-commands like ``nova-manage db sync``. The
+   ``nova-status upgrade check`` command was written in the same way for
+   consistency and extensibility if other sub-commands need to be added later.
+
+#. Where should the documentation live for projects other than nova?
+
+   As part of the standard OpenStack project `documentation guidelines`_ the
+   command should be documented under ``doc/source/cli`` in each project repo.
+
+#. Why is the upgrade check command not part of the standard python-\*client
+   CLIs?
+
+   The ``nova-status`` command was modeled after the ``nova-manage`` command
+   which is meant to be admin-only and has direct access to the database,
+   unlike other CLI packages like python-novaclient which requires a token
+   and communicates with nova over the REST API. Because of this, it is also
+   possible to write commands in ``nova-manage`` and ``nova-status`` that can
+   work while the API service is down for maintenance.
+
+#. Can upgrade checks only be for N-1 to N version upgrades?
+
+   No, not necessarily. The upgrade checks are also an essential part of
+   `fast-forward upgrades`_ to make sure that as you roll through each release
+   performing schema (data model) updates and data migrations that you are
+   also completing all of the necessary changes. For example, if you are
+   fast forward upgrading from Ocata to Rocky, something could have been
+   added, deprecated or removed in Pike or Queens and a pre-upgrade check is
+   a way to make sure the necessary steps were taking while upgrading through
+   those releases before restarting the Rocky code at the end.
