-# CI setup
-
-This document describes what services we use for testing GitLab and GitLab CI.
-
-We currently use four CI services to test GitLab:
-
-1. GitLab CI on [GitHost.io](https://gitlab-ce.githost.io/projects/4/) for the [GitLab.com repo](https://gitlab.com/gitlab-org/gitlab-ce)
-2. GitLab CI at ci.gitlab.org to test the private GitLab B.V. repo at dev.gitlab.org
-3. [Semephore](https://semaphoreapp.com/gitlabhq/gitlabhq/) for [GitHub.com repo](https://github.com/gitlabhq/gitlabhq)
-4. [Mock CI Service](../user/project/integrations/mock_ci.md) for local development

+## CI setup
+
+- On CE, the test suite only runs against PostgreSQL by default. We additionally
+  run the suite against MySQL for tags, `master`, and any branch that includes
+  `mysql` in the name.
+- On EE, the test suite always runs both PostgreSQL and MySQL.
