 This directory contains Tempest tests to cover Zun project.
 
+
+Tempest installation
+--------------------
+
+To install Tempest you can issue the following commands::
+
+    $ git clone https://github.com/openstack/tempest/
+    $ cd tempest/
+    $ pip install .
+
+The folder you are into now will be called ``<TEMPEST_DIR>`` from now onwards.
+
+Please note that although it is fully working outside a virtual environment, it
+is recommended to install within a `venv`.
+
+Zun Tempest testing sutup
+-------------------------
+
+Before using zun tempest plugin, you need to install zun first::
+
+    $  pip install -e <ZUN_SRC_DIR>
+
 To list all Zun tempest cases, go to tempest directory, then run::
 
     $ testr list-tests zun
 
+Need to adopt tempest.conf, an example as follows::
+
+    $ cat /etc/tempest/tempest.conf
+
+    [auth]
+    use_dynamic_credentials=True
+    admin_username=admin
+    admin_password=123
+    admin_project_name=admin
+
+    [identity]
+    disable_ssl_certificate_validation=True
+    uri=http://127.0.0.1:5000/v2.0/
+    auth_version=v2
+    region=RegionOne
+
+    [identity-feature-enabled]
+    api_v2 = true
+    api_v3 = false
+    trust = false
+
+    [oslo_concurrency]
+    lock_path = /tmp/
+
+    [container_management]
+    catalog_type = container
+
+    [debug]
+    trace_requests=true
+
 To run only these tests in tempest, go to tempest directory, then run::
 
     $ ./run_tempest.sh -N -- zun
 
 To run a single test case, go to tempest directory, then run with test case name, e.g.::
 
-    $ ./run_tempest.sh -- -N zun.tests.tempest.api.test_basic.TestBasic.test_basic
+    $ ./run_tempest.sh -- -N zun.tests.tempest.api.test_containers.TestContainer.test_create_list_delete
