I have been testing Quadrat (a child theme of Blockbase) since its first release. I have made some modification to use it in one of my learning project sites, but I have been struggling to find a beginner-friendly workflow resource to work with a child-theme.json to modify the original theme's theme.json.

I am familiar with the workflows of React, Gatsby and Frontity but wondering whether there was a how to set up guide to create block base child theme workflow? Or else, how to save modifications without compromising future theme updates.
