Documentation is scarce especially considering that Qrten is built for full site editing, enhancing some Gutenberg core modules and adding others. And Gutenberg itself still has a steep learning curve. You could find yourself in my situation to think the theme is broken. Wich is not.

Apart from some minor bugs, and If you don't want to make drastic changes to it, this is one of the best looking full site editing magazine themes without being too proprietary. Others have their article blocks, Qrten just uses the default Gutenberg ones with envirra enhancements on top. For now this made me to give Gutenberg another chance.
