+In order to use this discovery you have to install tempest CLI, be in the

-	run-tempest-stress -a -d 30
+	tempest run-stress -a -d 30
 
 Running the sample test
 -----------------------
 
 To test installation, do the following:
 
-	run-tempest-stress -t tempest/stress/etc/server-create-destroy-test.json -d 30
+	tempest run-stress -t tempest/stress/etc/server-create-destroy-test.json -d 30
 
 This sample test tries to create a few VMs and kill a few VMs.
