#     e.g. ./potato-build.sh 1.0.0
#  2. Alternatively, you can can run using docker compose
#     e.g. docker compose run --build potato
#  2a. To pass in an argument, either edit the .env file, 
#      or set a local environment variable: e.g. export VEGAN="--vegan"

# Tag for the built container
TAG=latest
