Erect the hood frame and throw the hood over the frame. Fasten the rear hood fixings first and then along the side.
Next come the fastenings to the windscreen frame; start in the middle and work your way fixing the outer ones.
It helps if the hood is warm as it will give the hood material greater flex and 'give' during assembly.
As for entry and egress, each to their own but I tend to enter one leg first, slide and bring the other leg into the car.
Enjoy your Plus Eight with or without hood erected!
