On the project README.md documentation, it saids that this project should not be used for production. Which means that it might not be stable yet.

Yet, on the ReactCommerce site, the documentation seems to point at using 2.0 and Next starter template seems to be the recommended approach based on that documentation over there.

This is somewhat confusing and concerning, and I am not sure what is stable to use in production, as well as provide the best developer experience.

What is the official recommended approached to customize the frontend as of January 21, 2019?
