+## Publishing Linux Repositories
+
+The `scripts/publish-repo.sh` script publishes DEB and RPM packages to Cloudflare R2 (served at `repo.donutbrowser.com`). It requires Linux tools, so run it in Docker on macOS:
+
+```bash
+docker run --rm -v "$(pwd):/work" -w /work --env-file .env -e GH_TOKEN="$(gh auth token)" \
+  ubuntu:24.04 bash -c '

+
+The `.github/workflows/publish-repos.yml` workflow runs automatically after stable releases and can also be triggered manually via `gh workflow run publish-repos.yml -f tag=v0.18.1`.
+
+Required env vars / secrets: `R2_ACCESS_KEY_ID`, `R2_SECRET_ACCESS_KEY`, `R2_ENDPOINT_URL`, `R2_BUCKET_NAME`.
