+# Ansible role for tests using basic scripts
+
+Put this role in your test_local.yml playbook. The playbook
+will first install package dependencies listed on playbook on
+your localhost, then it will proceed to run testing.
+You can redefine the following variables in
+roles/standard-test-basic/vars/main.yml:
+
+ * tests: A list of test cases
+ * artifacts: An artifacts directory on localhost to store logs
+ * remote_artifacts: The directory on the system under test
+     where the logs are stored.  Note: if this variable is left
+     undefined, it will default to /tmp/artifacts
+ * required_packages: A list of prerequisite packages required by
+     tests. Please note that for Atomic Host, additional
+     packages will be installed using the rpm-ostree command which
+     is affecting the test subject (it's similar as rebuilding an
+     rpm package to be tested) so this should be used with caution
+     and only when necessary.
