+# 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 Docker build
+# - Push the built image to an image registry
+# - Log in to your OpenShift cluster
+# - Create an OpenShift app from the image and expose it to the internet.
+
+### Before you begin:
+# - Have write access to a container image registry such as quay.io or Dockerhub.
+# - Have access to an OpenShift cluster.
+#   - For instructions to get started with OpenShift see https://www.openshift.com/try
+# - The project you wish to add this workflow to should have a Dockerfile.
+#   - If you don't have a Dockerfile at the repository root, see the buildah-build step.
+#   - Builds from scratch are also available, but require more configuration.
+
+### To get the workflow running:
+# 1. Add this workflow to your repository.
+# 2. Edit the top-level 'env' section, which contains a list of environment variables that must be configured.
+# 3. Create the secrets referenced in the 'env' section under your repository Settings.
+# 4. Edit the 'branches' in the 'on' section to trigger the workflow on a push to your branch.
+# 5. Commit and push your changes.
+
+# For a more sophisticated example, see https://github.com/redhat-actions/spring-petclinic/blob/main/.github/workflows/petclinic-sample.yaml
+# Also see our GitHub organization, https://github.com/redhat-actions/
