[NTG-context] A ConTeXt Guide in Italian

Hello everyone! This is my first message here. I'm trying to write a ConTeXt guide in Italian. The LaTeX *tcolorbox* package defines an environment dedicated to LaTeX examples: above (or on the left) the source is written, and below (or on the right) the typeset result. Is there something similar for ConTeXt? Does it make sense, in your opinion, to showing examples of source code with the related outputs in this way? Thanks in advance for any advice on this aspect of the guide and for any suggestions. Tommy
