What I don't understand: let's say I write a new issue with Quill and somehow get an issue title and markdown support. When this entry gets posted via Micropub to my website and webmentions are mentioned to https://brid.gy, how can Brid.gy convert the HTML from my entry back to Markdown in Github? Does it do that, or is there some other magic going on.
