Default sheet for Parrot? Crouton/Chromebooks

QUESTION: What code would be added to a Default sheet in order to create a folder for Parrot OS in Crouton? (Be kind - my partner is a Middle School student and we are both script kitties (BUT WE TRY HARD).

Currently, there’s a process to install a linux distro on a chromebook (for instance, (https://chromeready.com/4714/install-kali-linux-chromebook/))).

After a quick perusal of the code in the Crouton git repository, the main differences between the available linux distros (Ubuntu, Debian, and Kali) are found in “Defaults” and " Releases".

What seems to be key is in the “Defaults”. For example, this is what’s in Kali’s Defaults sheet:

if [ -z "$ARCH" ]; then
    ARCH="`uname -m`"
fi

case "$ARCH" in
x86 | i?86) ARCH="i386";;
x86_64 | amd64) ARCH="amd64";;
armel) ARCH="armel";;
arm64 | aarch64) ARCH="arm64";;
arm*) ARCH="armhf";;
*) error 2 "Invalid architecture '$ARCH'.";;
esac

if [ -z "$MIRROR" ]; then
    MIRROR="${CROUTON_MIRROR_kali:-http://http.kali.org}"
fi

if [ -z "$MIRROR2" ]; then
    MIRROR2="${CROUTON_MIRROR2_kali:-http://security.kali.org/kali-security}"
fi

BOOTSTRAP_RELEASE="stable"

Ubuntu, on the other hand, has this:

if [ -z "$ARCH" ]; then
    ARCH="`uname -m`"
fi

case "$ARCH" in
x86 | i?86) ARCH="i386";;
x86_64 | amd64) ARCH="amd64";;
arm64 | aarch64) ARCH="arm64";;
arm*) ARCH="armhf";;
*) error 2 "Invalid architecture '$ARCH'.";;
esac

# trusty is the first release with arm64
if [ "$ARCH" = "arm64" ] && release -lt trusty; then
    ARCH="armhf"
fi

if [ -z "$MIRROR" ]; then
    if [ "$ARCH" = 'amd64' -o "$ARCH" = 'i386' ]; then
        MIRROR="${CROUTON_MIRROR_ubuntu_x86:-http://archive.ubuntu.com/ubuntu/}"
    else
        MIRROR="${CROUTON_MIRROR_ubuntu_arm:-http://ports.ubuntu.com/ubuntu-ports/}"
    fi
fi
