 #### Run the regression test suite
 
-At this point you should be able to run the tests:
+The test suite has a dependency that the mysql client is installed on your laptop/machine where the test will be run.  This is needed in order to seed the mysql database that is running in the docker network.
+
+Assuming you have installed the mysql client, and done the above steps, you should now be able to run the tests:
