 # Install test dependencies
+# TODO(tflannag): This is a quick fix to kubebuilder's quick start instructions
+# that were failing e2e tests. We'll want to update our o/release ci-operator
+# configuration to allow build_root changes to be reflected in a PR vs.
+# instead of the CI pipeline always defaulting to building the HEAD version
+# of the dockerfile:
+# - https://docs.ci.openshift.org/docs/architecture/ci-operator/#build-root-image
+# Note(tflannag): We ran into some issues curling from the https://go.kubebuilder.io/dl
+# domain as the output file was HTLM-based, so curl from the github releases
+# until this has been resolved.
