It seems to be a no code markdown editor for creating a community high-level description and key aspects. The lack of what to do next with that is bothering me at least personally. I feel like there is some step of taking this a actually plugging in proccess and people that is missing.
I personally, at the moment, just see it as a nice way to make a strategic choice what you WANT a community to be. With the rest of something left as a to-do kind defined by the strategic requirements.
