Many thanks.
If you click the System icon to bottom right then select "active help" then "achievements", it's mentioned there on the second page of the tip. So I imagine it must've appeared the first time you got an achievement and popped up as a game tip/help. It's easy to forget/not notice, I forgot till I read about it at random.
