Roof assembly instructions:
Lay the roof construction in front of you with the printed image facing downwards and unfold all sides.
Insert both middle side flaps from the outside into the respective opening of the upper flap and hook the two parts together.
Fold in the bottom piece and clamp it behind the top flap to create the triangular roof.
Now there should only be one flap sticking out on each side, which you push into the top of the calendar so that the roof is fixed to the calendar.
