 Many of the OpenStack components have implemented API microversions.
-It is important to tests those microversion in Tempest or external plugins.
+It is important to test those microversions in Tempest or external plugins.
 Tempest now provides stable interfaces to support to test the API microversions.
 Based on the microversion range coming from the combination of both configuration
 and each test case, APIs request will be made with selected microversion.

+Standalone Plugin vs In-repo Plugin
+-----------------------------------
+
+Since all that's required for a plugin to be detected by tempest is a valid
+setuptools entry point in the proper namespace there is no difference from the
+tempest perspective on either creating a separate python package to
+house the plugin or adding the code to an existing python project. However,
+there are tradeoffs to consider when deciding which approach to take when
+creating a new plugin.
+
+If you create a separate python project for your plugin this makes a lot of
+things much easier. Firstly it makes packaging and versioning much simpler, you
+can easily decouple the requirements for the plugin from the requirements for
+the other project. It lets you version the plugin independently and maintain a
+single version of the test code across project release boundaries (see the
+`Branchless Tempest Spec`_ for more details on this). It also greatly
+simplifies the install time story for external users. Instead of having to
+install the right version of a project in the same python namespace as tempest
+they simply need to pip install the plugin in that namespace. It also means
+that users don't have to worry about inadvertently installing a tempest plugin
+when they install another package.
+
+.. _Branchless Tempest Spec: http://specs.openstack.org/openstack/qa-specs/specs/tempest/implemented/branchless-tempest.html
+
+The sole advantage to integrating a plugin into an existing python project is
+that it enables you to land code changes at the same time you land test changes
+in the plugin. This reduces some of the burden on contributors by not having
+to land 2 changes to add a new API feature and then test it and doing it as a
+single combined commit.
