-# Documentation
+# Testing CORD
 
-This directory contains docs related to
-* How to setup the test environment
-* How to execute tests on a given CORD POD
-* How to add additional use-cases
-* How to integrate the test environment into existing CD (Continuous Delivery)
-  pipelines.
+The _CORD Automated Tester Suite (CATS)_ is an extensible
+end-to-end system test suite targeting CORD PODs. It is typically
+deployed as one or more Docker containers, either on the CORD POD
+or adjacent to the POD and interacts with the POD through the
+PODs interfaces.
+
+Its intended use includes:
+
+* Regression testing for CORD related component development
+* Acceptance testing of a deployed CORD POD
+* Health-testing of an existing CORD POD (including non-service-impacting
+  and possibly service-impacting tests)
+
+The strength of the CATS will come from the collaboration of the whole CORD/ONOS
+community, and as such we welcome contributions.
