+# Artifact Hub reads it from a separate OCI artifact pushed to the chart repository under the special `artifacthub.io` tag:

+#   oras push oci.stackable.tech/sdp-charts/trino-operator:artifacthub.io \
+#     --config /dev/null:application/vnd.cncf.artifacthub.config.v1+yaml \

+# Enables the "Verified publisher" label in AH. Taken from the repository's card in
+# the Artifact Hub control panel. Not a secret.
+#
+# Every operator that gets this file has an ID. An operator without an Artifact Hub
+# repository excludes the file entirely via `ignored_files` in
+# config/repositories.yaml, the way druid does while it is being removed from SDP.
