-Repository to store the content on Enveloped JSON Signatures spun off from the discussion on WoT Security, e.g., https://github.com/w3c/wot-thing-description/pull/1151
+# Enveloped JSON Signatures
+This was spun off from Web of Things where a need was identified to add internal signatures to a WoT Thing Description.
+Current JSON signature mechanisms, e.g. JWS, are external and "enveloping", and in addition don't support useful features
+like chaining, partial signing (signing only a subset of the document), or multiple signatures.  The short-term goal of this
+repo is to define an extension that can be used in WoT TDs for signing.  The long-term goal is to establish a basis for
+an enveloped JSON signature standard that can be used for any JSON content.
