Nice! I suggest adding a link to in in the README

wget --continue --timestamping --show-progress https://tails.boum.org/tails-signing.key
wget --continue --timestamping --show-progress https://tails.boum.org/torrents/files/tails-amd64-6.8.1.iso.sig
gpg --import "tails-signing.key"
wget --continue --timestamping --show-progress https://mirrors.wikimedia.org/tails/stable/tails-amd64-6.8.1/tails-amd64-6.8.1.img
gpg --keyid-format 0xlong --verify tails-amd64-6.8.1.iso.sig tails-amd64-6.8.1.img

I think any kind of graphical application should have at least one screenshot linked in documentation/README
