+# This script mirrors the Knative images built by OpenShift CI to
+# quay.io. It also pushes tags to GitHub for each repository in the
+# release except knative-operators.
+#
+# For every new major or minor version, bump RELEASE_MAJOR_MINOR to
+# the correct value. If doing a patch release, the script may need to
+# be adjusted a bit. At a minimum, RELEASE_VERSION will need to be
+# updated to not assume the patch version is 0.
+#
+# Also check CI_TAGS and add/remove/rename any images if they've
+# changed since the last release.
+#
+# The definitive list of images for each repo in Knative can be found
+# by looking at the bottom of the build logs for each Knative release
+# promotion job at
+# https://openshift-gce-devel.appspot.com/jobs/origin-ci-test/logs/.
+#
+# For example,
+# https://openshift-gce-devel.appspot.com/builds/origin-ci-test/logs/branch-ci-openshift-knative-build-release-0.3-images/
+# and then click on the most recent job for the 0.3 release branch, view the entire log, and you'll see lines like:
