way to go

I'm a little stuck... Click here to teach me more about this clue!

'directions' is the definition.
(I've seen this before)

I don't understand the rest of the clue.

(Other definitions for way to go that I've seen before include "Well done" , "Directions" , "good job" , "Route to a destination - preferred course of action" , "Director gives one" .)
