 featureset override
 -------------------
 
+In TripleO CI, we test each patchset using different jobs. These jobs
+are defined using `featureset config files
+<http://git.openstack.org/cgit/openstack/tripleo-quickstart/tree/config/general_config>`_.
+Each featureset config file is mapped to a job template that is defined in
+`tripleo-ci <http://git.openstack.org/cgit/openstack-infra/tripleo-ci/tree/zuul.d>`_.
+Tempest tests are basically triggered in scenario jobs in order to post validate the
+a particular scenario deployment.
 The set of tempest tests that run for a given TripleO CI job is defined in the
 `featureset config files
-<https://github.com/openstack/tripleo-quickstart/tree/master/config/general_config>`_.

 You may want to run a popular TripleO CI job with a custom set of Tempest
 tests and override the default Tempest run. This can be accomplished through
-`featureset_override` group of vars in Zuul job config. This setting allows
-projects to override featureset post deployment configuration. The overridable
-settings are:
+adding the `featureset_overrides` var to zuul job config `vars:` section.
+The list of custom featureset_override are defined in `zuul-v3.yaml
+<http://git.openstack.org/cgit/openstack-infra/tripleo-ci/tree/playbooks/tripleo-ci/run-v3.yaml>`_.
+This setting allows projects to override featureset post deployment configuration.
+The overridable settings are:
 
  - `run_tempest`: To run tempest or not (true|false).
  - `tempest_whitelist`: List of tests you want to be executed.
  - `test_black_regex`: Set of tempest tests to skip.
+ - `tempest_format`: To run tempest using different format (packages, containers, venv).
+ - `tempest_extra_config`: A dict of additional tempest config to be overridden.
+ - `tempest_plugins`: A list of tempest plugins needs to be installed.
