-## Purpose
-
-`test-ubuntu-git` is a container image hosted on the GitHub Container Registry, `ghcr.io`.

-It is intended primarily for testing the [`actions/checkout` repository](https://github.com/actions/checkout) as part of `actions/checkout`'s CI/CD workflows.
-
-The composition of `test-ubuntu-git` is intentionally minimal.  It is comprised of [git](https://git-scm.com/) installed on top of a [base-level ubuntu image](https://hub.docker.com/_/ubuntu/tags).
-
-# License
