how do you do this?

I am climbing up this ladder and then it stops and there is a spot to jump in. You need to do like a v jump or something, but i was trying to get in the spot, and three kids were laughing at me.

Is it the one where there is like a ladder to the side, and the boxes going up right on the side of it? and there is one empty space?
If so , there is a guide on it and alls you do is like line your guys shoulders up with the base of the opening, and then u just jump and crouch.
