Hi Giulia,
The tutorial link I sent in the previous message covers that part.

You can generalize, i.e. you don't have to follow all the steps, just the ones that do the things you want like positioning the two parts, and you could use different display styles (spheres rather than molecular surface, for example), coloring, etc.
