+# Mock CI Service
+
+**NB: This service is only listed if you are in a development environment!**
+
+To setup the mock CI service server, respond to the following endpoints
+
+- `commit_status`: `#{project.namespace.path}/#{project.path}/status/#{sha}.json`
+   - Have your service return `200 { status: ['failed'|'canceled'|'running'|'pending'|'success'|'success_with_warnings'|'skipped'|'not_found'] }`
+   - If the service returns a 404, it is interpreted as `pending`
+- `build_page`: `#{project.namespace.path}/#{project.path}/status/#{sha}`
+   - Just where the build is linked to, doesn't matter if implemented
+
+For an example of a mock CI server, see [`gitlab-org/gitlab-mock-ci-service`](https://gitlab.com/gitlab-org/gitlab-mock-ci-service)
