 ## How It Works
 
+### Promoting features on release
+
+After cutting an SDK release, maintainers manually prepare and submit the
+registry port update. There is no release-triggered workflow that creates a
+vcpkg PR, and no repository token is needed for port preparation.
+
+The [preparation helper](../.github/scripts/prepare-vcpkg-release.py) copies the
+**complete overlay port from the release tag**, not from the current development
+branch. It then replaces the archive
+`REF`, `SHA512`, and manifest version and removes any old `port-version`. This
+carries feature declarations and their CMake wiring together, including
+`minimal-sqlite` and the explicit Android curl backends. Run it from the released
+SDK checkout against a separate vcpkg checkout outside the SDK source tree.
+Start with a clean vcpkg working tree: the helper replaces the destination port,
+including existing patches. Before replacing it, the helper resolves the
+destination and requires both `.vcpkg-root` and
+`scripts/buildsystems/vcpkg.cmake` in the inferred vcpkg checkout.
+The helper requires Python 3.10 or newer and uses only the standard library.
+Pass the four-component version **without** its `v` prefix and the SHA512 of the
+published GitHub source `.tar.gz` archive, not an xcframework, AAR, or ZIP:
+
+```console
+python .github/scripts/prepare-vcpkg-release.py --source-port tools/ports/cpp-client-telemetry --destination-port <vcpkg>/ports/cpp-client-telemetry --version X.Y.Z.W --sha512 <release-archive-sha512>
+```
+
+Run `vcpkg format-manifest` on the resulting manifest and validate the downloaded
+release with `MATSDK_VCPKG_SOURCE_DIR` unset and without the SDK overlay before
+submitting the registry PR. Cover the default graph and the advertised opt-in
+features. Do not use the `tests/vcpkg` scripts for this release validation: they
+intentionally build the local SDK checkout instead of the pinned archive.
+The helper does not build, commit, push, or open a PR. After validating the port,
+commit its changes, update the vcpkg version database, and submit the registry PR
+using your normal local GitHub authentication.
+
+### Dependency and transport selection
+
 The SDK consumes canonical CMake dependency targets. The vcpkg toolchain
 provides those targets through normal `find_package()` discovery; no separate
 SDK-specific dependency-mode switch is required. Android transport selection is
