# This demo uses an alpine sandbox in a docker container in 
# interactive mode. ran with:
#    docker run --rm -it alpine
#
# if you run it on your own system:
#  1. you should use your own package manager instead of `apk`
#  2. expect the following left overs:
#    - installed binaries (age, age-keygen, sops)
#    - $HOME/.config/sops/age/keys.txt 
#    - demo files: source.env, encrypted.env, decrypted.env

Given that the factory is already implemented, how easy is it to add a new case.

Mind how hoisting helps keep the higher levels above, while implementation details are below.
