## Description The third-party mirroring guide describes image layers as stored on `dhi.io`, which makes it unclear why the examples use Docker Hub for images and the Scout registry for attestations. Clarify that `dhi.io` provides access to DHI catalog images and their signed attestations, while customer mirrors and customized images in organization repositories are accessed through Docker Hub. This explains why the examples copy images from Docker Hub and attestations from `registry.scout.docker.com` into the same destination repository. Copying only the image does not preserve its attestations. The proxy's repository routing rejects names containing `/` and maps accepted names into the `dhi/` namespace: [routing implementation](https://github.com/atomisthq/dhi-proxy/blob/e47c68d6473b2b45a4aeb3be55808eee58902732/internal/proxy/middleware.go#L161-L188). The public [image reference documentation](https://docs.docker.com/dhi/how-to/use/#pull-run-and-reference-dhis) also distinguishes catalog references on `dhi.io` from organization repositories on Docker Hub. ## Reviews - [ ] Technical review - [ ] Editorial review - [ ] Product review ## Validation - `npx --no-install rumdl fmt content/manuals/dhi/how-to/mirror.md` - `scripts/lint.sh content/manuals/dhi/how-to/mirror.md` with repository-pinned rumdl 0.2.49 and Vale 3.17.0: no errors, warnings, or suggestions - `git diff --check` This is a prose-only change. The mirroring commands are unchanged. A full site build was not run. --------- Signed-off-by: Brian Rubinton <brian.rubinton@docker.com>
