[NTG-context] Lucida (from a newbie) question

Hello I'm trying to switch from plain TeX (with my own set of macros) to ConTeXt. I bought the Lucida fonts and I wish ti use them. I don't find how to do this on my Mac-Live with TexShop install. I promise I've read anything I could find on the ConTeXt wiki. Thank's by advance.
