How to run it?

[nobrowser]

Sorry, this probably looks like a really stupid question. But you see, I am not a JS person, or a Web person. I am just desperate to find a SGF editor I can use on a GNU/Linux system. So how do I actually start this application? Do I need a browser? Do I need to be online? What file to open?

Maybe there is a bug here: this could be mentioned in README.md ?
