# This is a convenience script that can be downloaded from GitHub and

# curl -fsSL https://raw.githubusercontent.com/open-sauced/pizza-cli/main/install.sh | sh

# Warning: It may not be advisable to pipe scripts from GitHub directly into
# a command line interpreter! If you do not fully trust the source, first
# download the script, inspect it manually to ensure its integrity, and then
# run it:
#
# curl -fsSL https://raw.githubusercontent.com/open-sauced/pizza-cli/main/install.sh > install.sh
# vim install.sh
# ./install.sh
