 ## Notes
+- Host ports: app **18080**, Postgres **5544** (chosen to avoid clashing with your other
+  local containers). Change them in `docker-compose.local.yml` if needed.
 - If `mcr.microsoft.com` isn't reachable on your machine, edit `Dockerfile.local` and swap the
   two `FROM mcr.microsoft.com/dotnet/...` lines for `mirror.soroushasadi.com/dotnet/...`.
 - Same for the Postgres image (`postgres:16-alpine` → `mirror.soroushasadi.com/postgres:16-alpine`).
