Requires Javascript to even start showing the text. That "live" editor trick is neat, but pretty unnecessary to transmit the message, if you ask me. Also there are some good-old links that are not even clickable. Weird choice of tool for the job.
Just as YAML provides no validation document, intellisense or type safety this website is designed to be a hindrance. It's part of the message to make the experience more real. I do accept PRs tho so mash the octocat.
