 =================================
-These script can be run to tests of GitLab CE on a [configured](configure_a_runner_to_run_the_gitlab_ce_test_suite.md) runner.

 # Build script used at ci.gitlab.org to test the private GitLab B.V. repo at dev.gitlab.org
+This build script can run both with the docker or shell executor in [gitlab-ci-multi-runner](https://gitlab.com/gitlab-org/gitlab-ci-multi-runner).
+
+If you are using a shell executor, runner must be configured to have mysql and ruby, see a [configuration example](https://gitlab.com/gitlab-org/gitlab-ci/blob/master/doc/examples/configure/ruby.md).
