-- **For projects with no `.gitlab-ci.yml` present:**
-  A pipeline needs to be triggered either by pushing a new commit to the
-  repository or manually visiting `https://example.gitlab.com/<username>/<project>/pipelines/new`
-  and creating a new pipeline for your default branch, generally `master`.
-- **For projects with a `.gitlab-ci.yml` present:**
