+## This script helps to run docker buildx to build cross-arch/platform packages (linux only)
+## It mounts (not copy) host directory to a cross-arch/platform builder container
+## Make sure the source dir (specified by --src_dir option) is clean before running this script
+
+## NOTE: it requires $USER in docker group
+## i.e. will not work if docker command has to be executed with sudo
+
+## example:
+## ./scripts/buildx.sh --profile emqx --pkgtype zip --builder ghcr.io/emqx/emqx-builder/4.4-4:24.1.5-3-debian10 --arch arm64
