Q: How to contribute React and Vue versions of the Codelabs Tutorial?

Thanks for [the wonderful codelabs tutorial!](https://codelabs.developers.google.com/codelabs/firestore-web)

My friends mainly @isamu and others incl. myself have made React and Vue version of the codelabs tutorial (with English and Japanese) and are willing to contribute it back to the community. Could you kindly tell me what is the best way to move forward if it is ever possible?

Followings are the repos (currently the tutorial texts are defaulted to Japanese but English ones are also included):

- React Version: https://github.com/isamu/FriendlyEats-vue
- Vue Version: https://github.com/isamu/FriendlyEats-React

Thank you in advance!
