+## Cleaning Up
+
+Every build first writes images to the https://hub.docker.com/r/rapidsai/staging repo on DockerHub,
+then pushes them on to the individual repos like `rapidsai/base`, `rapidsai/notebooks`, etc.
+
+A scheduled job regularly deletes old images from that `rapidsai/staging` repo.
+See https://github.com/rapidsai/workflows/blob/main/.github/workflows/cleanup_staging.yaml for details.
+
+If you come back to a pull requests here after more than a few days and find that jobs are failing with errors
+that suggest that some necessary images don't exist, re-run all of CI on that pull request to produce new images.
