Messenger without Facebook account on Windows Phone?

[Windows Central Question]

I'm trying hard to be original - that's why I don't have Facebook account and use Windows Phone. And try to imagine my happiness, when, several months ago, I heard that I will be able to comunicate with my friends without sending them letters - Facebook is introducing Messenger for non-facebookers! In Android the thing works perfect. Windows is more problematic. Does anyone know, if this option is available on my Lumia? I've already tried to spam Facebook with questions, but reaching them without having an account is impossible. And, of course, sorry for my English.
