Shouldn't this link directly to GitHub instead? (https://github.com/SnabbCo/snabbswitch)
Also, just in case the author of Snabb Switch is reading this, it would be really helpful to provide a short example program of how to use this. A brief look over the documentation didn't show anything. (It's possibly I just missed it. In which case it would be great if you linked to it in the README or otherwise made it prominent).
