+README:
+
+This CSAR contains all definitions that are required for deploying a simple
+vRNC(virtual Radio Network Controller) on a cloud.
+
+Entry information for processing through an orchestrator is contained in file
+TOSCA-Metadata/TOSCA.meta. This file provides high-level information such as
+CSAR version or creator of the CSAR. Furthermore, it provides pointers to the
+various TOSCA definitions files that contain the real details.
+The entry 'Entry-Definitions' points to the definitions file which holds the
+service template for the workload.
+'Entry-Definitions' is optional. An orchestrator can also process the contents
+like this:
+1) Read in and process each definitions file.
+2) For each definitions file:
+  2.1) Read in all * type definitions (node types, capability types, etc.) and
+       store them in an internal map
+3) Verify and build dependencies (e.g. inheritance) between all type definitions
+   previously read in. Orchestrator built-in types (e.g. TOSCA base types) are
+   also considered in this step.
+4) Process the actual service template (the file with a node_templates section).
+   Validate using previously obtained type information.
