+# HOW TO RUN THE POTATO IMAGE
+#  1. Run this script and pass in an optional prepare type argument
+#     e.g. ./potato-run.sh "--vegan"
+#  2. You can run using docker compose run
+#     e.g. docker compose run --build potato (builds the container before running)
+#     e.g. docker compose run potato (if you already built it)
+#     e.g. docker compose run potato --rm (removes the container upon exit)
+#  2a. To pass in an argument, either edit the .env file, 
+#      or set a local environment variable: e.g. export VEGAN="--vegan"
+#  3. You can run using docker compose up and passing in the --build arg
+#     e.g. docker compose up --build
+#  3a. Make sure to clean up containers since compose up doesn't have a --rm option
+#     e.g. docker container rm potato-potato-1
+
+
+# Preparation type for the built potato container
+PREPARE_TYPE="--nonvegan"
+
+if ! [ -z $1 ]; then
+    if [[ $1 == "-h" || $1 == "?" ]]; then
+        # Print usage
+        echo "Usage: $0 <prepare type>"
+        echo "Example: $0 --vegan"
+        exit 0
+    else
+        PREPARE_TYPE=$1
+    fi
+fi
+# Check if Docker is installed
+if ! [ -x "$(command -v docker)" ]; then
+    echo "You need to install Docker."
+    exit 1
+else
+    echo "Running Potato with argument: \"$PREPARE_TYPE\""

+# Perform the build
+docker run -it --name potato-in-a-container --rm -e VEGAN=${PREPARE_TYPE} potato:latest
