-## JSON schemas and examples
+## JSON schemas for ValueFlows
 
-This directory is to work with the [Secure Scuttlebutt](https://www.scuttlebutt.nz/) gang on using ValueFlows vocabulary to experiment with creating an economic layer on top of the ssb gossip network, using ssb messages.  
+Included here are json-schemas for the vocabulary needed for a ValueFlows app, including the vocabulary in the VF namespace, as well as the external pieces of vocabulary we are re-using.  This is current as of VF release .3.
 
-The schemas and examples here are not meant to be definitive, and in some cases have short-cut the VF vocabulary to create smaller scoped examples to try out.  It is all experimental, and tailored to this experiment right now.
+Questions, feedback, and issues welcome.
