+# This workflow uses actions that are not certified by GitHub.
+# They are provided by a third-party and are governed by
+# separate terms of service, privacy policy, and support
+# documentation.
+
+# 💁 The OpenShift Starter workflow will:
+# - Checkout your repository
+# - Perform a container image build
+# - Push the built image to the GitHub Container Registry (GHCR)
+# - Log in to your OpenShift cluster
+# - Create an OpenShift app from the image and expose it to the internet
+
+# ℹ️ Configure your repository and the workflow with the following steps:
+# 1. Have access to an OpenShift cluster. Refer to https://www.openshift.com/try
+# 2. Create the OPENSHIFT_SERVER and OPENSHIFT_TOKEN repository secrets. Refer to:
+#   - https://github.com/redhat-actions/oc-login#readme
+#   - https://docs.github.com/en/actions/reference/encrypted-secrets
+#   - https://cli.github.com/manual/gh_secret_set
+# 3. (Optional) Edit the top-level 'env' section as marked with '🖊️' if the defaults are not suitable for your project.
+# 4. (Optional) Edit the build-image step to build your project.
+#    The default build type is by using a Dockerfile at the root of the repository,
+#    but can be replaced with a different file, a source-to-image build, or a step-by-step buildah build.
+# 5. Commit and push the workflow file to your default branch to trigger a workflow run.
+
