+# The way this works is the following:
+#
+# The publish-docker-image job runs when a release is created, hence after post-release job.
+# The steps are:
+#  - Log in to the Container registry (example: ghcr.io/create-ci).
+#  - Extract metadata (tags, labels) for Docker image.
+#  - Build and push Docker image to the container registry.
+#    Image tags are "latest" and the semver tag (without the "v" prefix).
+#  - Generate artifact attestation.
+#
+# Reference:
+# https://docs.github.com/en/actions/use-cases-and-examples/publishing-packages/publishing-docker-images#publishing-images-to-github-packages
