+## Pre Build Packages

+You can use
+[automated build container images](https://github.com/wide-vsix/linux-flow-exporter/pkgs/container/linux-flow-exporter/versions?filters%5Bversion_type%5D=tagged) or
+[automated build elf-binary](https://github.com/wide-vsix/linux-flow-exporter/releases).
+Both are automatically created by updating main-branch and creating release.
+Please note that flowctl depends on clang, iproute2 and linux kernel.
+You can use `flowctl dependency-check` to check for dependency problems.
