You can use this template if you want to create a new game from scratch, without any additional auto-processing.
After editing the game, you can build it by executing following command:
cd folder-of-this-game
node ../games-builder/build-game.js game.html
If you do not have the game builder yet, you can obtain it from it's repository.
After executing, the dist
folder will be created. There, you can find several files, including .svg
image with the working QR code.
