[Network-Centric Resources] collaborative markdown editor

[Floriana]

Hi everybody,
I've just found out about this project: https://github.com/hackmdio/hackmd

It's a collaborative markdown editor that might be interesting for some
of our documentation projects based on git+markdown. You can see an
instance here: https://pad.unixcorn.org/

Has anybody tried it out, and does someone have opinions on it?

Thank you,
Flo
