+# M-CORD tests
+
+This directory contains a simple playbook for creating an M-CORD EPC and
+verifying that it comes up correctly. It can be run on any node with Ansible
+installed and SSH connectivity to the master node of the openstack-helm
+installation.
+
+Invoke the playbook as follows, where "masternode" is the DNS name of the
+master node:
+
+```
+ansible-playbook -i masternode, mcord-cavium-test-playbook.yml
+```
+
+The comma after "masternode" is important; it allows Ansible to run the
+playbook on the remote node without having to specify an inventory file.
