I see it when I go to that URL, at least now. Thank you for building and pushing that!
One comment: this seems to be the standard ocamldoc style output, without much in the way of introductory material and the rest, which makes it pretty hard for a beginner to make heads or tails of what they’re reading.
I’m very interested in doing some PPX work, but I’ve found it quite confusing working with the panoply of libraries and tools. Better documentation will be a big help here! See the long discussion here: OCaml Documentation Open Thread for some discussion of OCaml documentation.
