Not really, it should work ok-ish on Linux as is (a good chunk of it was developed on Ubuntu). OSX is supported "by chance" I don't own a Mac I can test on. I was meaning to include a readme with basic information and a license too, but it seems I never got to doing it! I'll fix that.
If you're talking about commands starting shells, then it's true Windows is where they will work best at the moment, though.
