+synopsis:            JSON to YAML Adapter
+description:
+  The [YAML 1.2](https://yaml.org/spec/1.2/spec.html) format provides
+  a much richer data-model and feature-set
+  than the [JavaScript Object Notation (JSON)](https://tools.ietf.org/html/rfc7159) format.
+  However, sometimes it's desirable to ignore the extra capabilities
+  and treat YAML as if it was merely a more convenient markup format
+  for humans to write JSON data. To this end this module provides a
+  compatibility layer atop [HsYAML](https://hackage.haskell.org/package/HsYAML)
+  which allows decoding YAML documents in the more limited JSON data-model while also providing
+  convenience by reusing [aeson](https://hackage.haskell.org/package/aeson)'s
+  'FromJSON' instances for decoding the YAML data into native Haskell data types.
