+#!/bin/sh
+# Build mikrotik-tailscale images for all supported MikroTik architectures.
+#
+# Produces one OCI image per architecture and, optionally, a per-arch tarball
+# suitable for `/container/add file=...` on RouterOS.
+#
+# Usage:
+#   ./build.sh                 # build all arches, load into local docker
+#   ./build.sh arm64           # build a single arch
+#   ./build.sh --tar           # build all arches and export .tar files
+#   ./build.sh --tar arm64     # build one arch and export its .tar
+#
+# Requirements:
+#   - docker with buildx
+#   - For non-native targets: binfmt/QEMU emulators registered, e.g.:
+#       docker run --privileged --rm tonistiigi/binfmt --install arm64,arm
+set -eu
