+## How do I run the tests?
+
+There are two main options for running the tests. If you simply want to run the
+existing tests against a live GitLab instance or against a pre-built docker image
+you can use the [GitLab QA orchestrator][gitlab-qa-readme]. See also [examples
+of the test scenarios you can run via the orchestrator](https://gitlab.com/gitlab-org/gitlab-qa/blob/master/docs/what_tests_can_be_run.md#examples).
+
+On the other hand, if you would like to run against a local development GitLab
+environment, you can use the [GitLab Development Kit (GDK)](https://gitlab.com/gitlab-org/gitlab-development-kit/).
+Please refer to the instructions in the [QA README](https://gitlab.com/gitlab-org/gitlab-ce/tree/master/qa/README.md#how-can-i-use-it)
+and the section below.
