+description: |
+  This is a JSON-Schema description of a 'chunk' .morph file, which is part of
+  the Baserock definitions YAML representation format.
+
+  This JSON-Schema file is valid for VERSION 7 of the Baserock definitions
+  YAML serialisation format.
+
+  The Baserock definitions format is the recommended way of representing
+  Baserock definitions on disk. The actual data model is described separately.
+  See https://wiki.baserock.org/definitions for more information.
+
+  This schema is represented as YAML, so that it can be edited more easily.
+  You may need to convert to JSON if using a JSON-Schema tool that expects
+  its input to be an actual string containing data serialised as JSON.
