The generator should not be an submodule of this project.

The generator (a.k.a CCIP-Puzzle-Configuration-Generator-Chocolate) is an option for creating configuration file of game. It is not necessary for this project.

There are some way to keep relationship include version between generator and this project:

1. Add an link with simple description for generator on README.md of this project
2. Instead of submodule, build-config.sh and config.json, add generator as an optional dependency package into package.json and use npm run <script> which defined inside package with given <spreadsheet keys> from stdin to generate configuration file.
