# git submodule update --remote

# It needs TW as dev env. One of option is to use distrobox as shown:
# ```sh
#   distrobox create --image tumbleweed --name zyppng
#   distrobox enter zyppng # if stuck see https://github.com/89luca89/distrobox/issues/1530 and kill and run again
#   # and now you are inside dev env where you run this script
#   # to clean use distrobox stop zyppng and if no longer image is needed use distrobox rm zyppng
# ```
