Are you intending to add the text under introduction.scheme.org?
https://books.scheme.org/ lists several published books by well known
schemers which are introductions to Scheme. https://docs.scheme.org/ has
more which are digitally published. If a prominent subdomain like
introduction.scheme.org is created, the canonical texts written by
experts should take precedence over brand new texts written by newcomers.

Even our most famous book SICP does not (currently) have its own
subdomain; it is published under https://docs.scheme.org/sicp/. It's
wonderful that Jakub put a lot of effort into making a nice and
up-to-date tutorial, but I suggest adding it under
https://docs.scheme.org/. (Either as a link or as a copy of the full
text - I have no preference.)
