+# TOSCA Interface
 
-The `xos-tosca` container is responsible to autogenerate the TOSCA interface starting from the `xproto` definition.
+A TOSCA interface is available for configuring and controlling CORD. It is 
+auto-generated from the set of [models](xos/README.md) configured 
+into the POD manifest, and includes both core and service-specific models.

 ## What is TOSCA?
 
-Topology and Orchestration Specification for Cloud Applications (TOSCA), is an OASIS standard language to describe a topology of cloud based web services, their components, relationships, and the processes that manage them. The TOSCA standard includes specifications to describe processes that create or modify web services.

-## Overview
+The `xos-tosca` container autogenerates the TOSCA interface starting
+from the `xproto` definition.  When the `xos-tosca` container starts,
+it connects to `xos-core`
+via the `gRPC` API to fetch all the `xproto` definition of the
+onboarded models. This includes both `core` and `service` models.
+Then using the `xos-genx` toolchain, it will generates the
+corresponding TOSCA specifications.
