+Running Policy Regression Tests:
+  ACM regression tests can be invoked using the script docker/csit/run-acm-regression.sh with the arguments {ACM-R release name} {participant release name}
+  For example, if ACM-R and participants needs to be tested for backward compatbility between montreal and london versions, the script can be invoked 
+  with the command "./run-acm-regression.sh montreal london"
+  This will deploy ACM-R and other policy components in montreal version and the participants in london version before invoking the test suite.
+  The script can also be invoked without any arguments to deploy all the components in the default version of the repo.
