Well lucky for you I like building content but lack experience in building engines (something I’d love to learn). Happy to contribute when I have some time. Email is in my profile if you feel like reaching out.
What a coincidence! In case you are also using discord there is a lonely server linked in the README. Feel free to hop in and don't worry about time. There are no strings attached. I'm in no rush and this is a fun-first project :)
