Stripe has a good poast about this, but probably overkill for now https://stripe.com/blog/markdoc

I'm not sure if this should be a separate app - there are debates about prerendering / static crap and markdoc ^ alternatives. Should research a bit but i believe Remix would work for everything we are trying to do.
