I wouldn't say not a big nor particularly difficult job. General socket set should get you through it. Make sure you have a second person for holding the bonnet when the bolts are undone.
Open the bonnet and put on the bonnet stay. Bottom left side and right side you will see a bracket with two bolts (approx 13mm head). Slacken them off the bonnet will move slightly don't fully remove at that point. Get the second person to hold the bonnet so it doesn't drop and either hit the screen or top of the wings. Do one side at a time. Lift it clear of the car. Fitting, opposite of removal lol just check it's aligned with previous marks before attempting to drop it shut.
