    <<~EOS
      To configure Docker to use ATCR credential helper, add the following
      to your ~/.docker/config.json:

      {
        "credHelpers": {
          "atcr.io": "atcr"
        }
      }

      Note: The credential helper name is "atcr" (Docker automatically prefixes
      with "docker-credential-" when looking for the binary).

      To authenticate with ATCR:
        docker push atcr.io/<your-handle>/<image>:latest

      This will open your browser to complete the OAuth device flow.

      Configuration is stored in: ~/.atcr/device.json
