+# Tests Service
+
+The tests service is for end to end testing
+
+## Overview
+
+This is a future service for end to end testing which either comes pre-built with integration tests in the 
+integration sub directory or with tests which are register via an endpoint Tests.Register for a callback 
+which then conforms to our testing API.

+# Integration Tests
+
+This directory includes integration tests for m3o services
+
+## Overview
+
+This directory is for tests built into the tests service. In future there may be a integration.Register endpoint 
+and we just import the various tests from wherever they are but for they are standard go tests run when the 
+m3o flag is passed for integration testing
