+Using Execute Test 
+======================================
+
+Used to run Tempest from Refstack: `refstack/tools/execute_test.py`
+
+Command Line
+--------------------------------------
+
+* tempest-home: path to tempest, e.g. /tempest
+* callback: url to post results formatted as ${api_addr} ${test_id}"
+
+Environment Variables
+--------------------------------------
+
+Instead of a configuration file, you can also start Execute_Test using environment variables.
+
+Required:
+* OS_AUTH_URL : Keystone URL
+* OS_REGION_NAME : Region
+* OS_USERNAME : Username
+* OS_PASSWORD : Password (passed in clear, do not save into file!)
+* OS_TENANT_NAME : Tenant name or ID
+
+Optional:
+* test_id : System Generated, may be overridden
+* api_addr
+* TEMPEST_IMAGE_REF: name of image used for testing.  Defaults to "cirus"
