-The backend build exports its complete BuildKit cache to
-`.build-cache/backend`. This directory includes the intermediate Nuitka build
-layers. Keep it to reuse the compiled result after Docker removes its internal
-build cache. The directory can be large and is excluded from Git and the Docker
-build context.
-
 The Python builder image is pinned to a tested image digest. Update this digest
 deliberately when the compiler environment needs an update. A runtime base
-image update does not invalidate the Nuitka build layer.
+image update does not invalidate the Nuitka build layer. Docker reuses its
+normal internal build cache. A complete build is necessary after that cache is
+removed.
 
 By default, the API is available at `http://localhost:17777/api`. Swagger UI is
 available at `http://localhost:17777/api/doc`.
