# =======================

# make sure `unzip` and `tar` are installed using
pkg install unzip tar

# unzip the artifact (if you have a different architecture this might be arm, i686 or x86_64 instead)
unzip debs-aarch64-*.zip

# untar the artifact
tar xf debs-aarch64-*.tar

# You should now have a debs/ directory in your current working directory
