I always used a unix environment to work and like it. I'm also a creative guy, sometimes I do graphism, design and don't like to switch OS to enjoy doing both. I heard of WSL and saw this as the forgotten messiah, so here a guide to install everything you will have to set up to enjoy both like me.

        this.getName = function() {
            return name;
