Check out somewhere (I personally put in in %USERPROFILE%\.yari)
> cd %USERPROFILE% > git clone git://github.com/scottmuc/yari.git .yari
Add this location to your PATH
> setx PATH %USERPROFILE%\.yari\bin
Note: if you already have something in your USER PATH environment variable this will overwrite it. I'm working on fixing this.
