-Deckhand is a storage service for YAML-based configuration documents, which are
-managed through version control and automatically validated. Deckhand provides
-users with a variety of different document types that describe complex
-configurations using the features listed below.
+Deckhand provides document revision management, storage and mutation

-Testing
--------
-
-Automated Testing
-^^^^^^^^^^^^^^^^^
-
-To run unit tests using sqlite, execute:
-
-::
-
-    $ tox -epy27
-    $ tox -epy35
-
-against a py27- or py35-backed environment, respectively. To run individual
-unit tests, run:
-
-::
-
-    $ tox -e py27 -- deckhand.tests.unit.db.test_revisions
-
-for example.
-
-To run functional tests:
-
-::
-
-    $ tox -e functional
-
-You can also run a subset of tests via a regex:
-
-::
-
-    $ tox -e functional -- gabbi.suitemaker.test_gabbi_document-crud-success-multi-bucket

 Overview
 ========
 
-Deckhand is a storage service for YAML-based configuration documents. Deckhand
-stores the documents using version control: Each time a collection of documents
-is passed to Deckhand, a new revision is created. Thus, documents have a
-revision history, allowing complex configurations to be incrementally modified
-and validated. For example, if the first revision of documents fail validation,
-deployers can make modifications to the documents and submit them to Deckhand
-again, until the documents pass validation and are ready to be rendered into
-their finalized state.
+Deckhand provides document revision management, storage and mutation
+functionality upon which the rest of the `Airship`_ components rely for
+orchestration of infrastructure provisioning. Deckhand understands declarative
+YAML documents that define, end-to-end, the configuration of sites: from the
+hardware -- encompassing network topology and hardware and host profile
+information -- up to the software level that comprises the overcloud.
