@@ -6,5 +6,6 @@ TypeSchema is a JSON format to describe data models in a language neutral format
 easily transformed into code for almost any programming language. This helps to reuse core data models in different
 environments. More information at: [https://typeschema.org](https://typeschema.org)
 
-The TypeSchema specification is developed at the [TypeHub platform](https://app.typehub.cloud/d/typehub/typeschema)
-which is a collaborative platform to design TypeSchema and TypeAPI specifications.
+The TypeSchema meta specification which describes the specification itself is located at `./specification/typeschema.json`.
+We automatically push the specification to the [TypeHub platform](https://app.typehub.cloud/d/typehub/typeschema) where
+you can see also a rendered version of the specification and download the auto generated models.
