Here's An Alternative, Until This Repo Is Updated...
I'm sad to see that this project is no longer being maintained, it looked like a really great tool that I would have enjoyed using. I've noticed that the repo for the JavaScript library has been updated recently so we might see an update to the reader, maybe? Until then, I have found an alternative called Bibi in case anyone is interested. Bibi is pretty much the same usage wise, the docs are a lot better though. Check it out.
(I am not the developer for Bibi or associated with them, I just bumped into it and thought others would like to know)
Thanks, that seems useful (though the docs are just in japanese for some reason)
Pretty much everything you need to get started is in the README file, are you looking at the website?
