reffing/unreffing tutorial

[DANIELLLANO <DANIELLLANO terra es>]

I've seen this and I think there should be a tutorial of the
reffing/unreffing thing. Not many people including me knows how
references should be taken care of.
Is there and easy tutorial of reffing/unreffing?
Is anyone willing to make one?
