I like it, it's much better than what I've used previously.

I made a docker container to run it (https://github.com/na4ma4/docker-yark), when I get time I'll do a PR if you're interested so it isn't a separate project.

(I'll also fix it so the host is a command line argument not just changing the binding from 127.0.0.1 to 0.0.0.0)
