you will need to measure correctly, first allow 10mm clearance on the width and height.also if the door is opening in you will need a (add on) 15-20mm thick lenth of plastic to allow the hinge to pass the plaster on the inside,this is important.
Always fix the hinge side first,make sure the threasholds level.To do this you will need plastic packers.
Once the hinge side is fixed, close the door slowly and eye the frame so its inline with the door.Dont fix the lock side plumb,the doors plastic and will be slighly bent so when you shut the door, the frame must line in with the door not the other way round.
Use stardrive fixings to fix the frame,use 3 or 4 on each side,2 in the cill.Pre drill the frame first it will be reinforced with steel.
you need your fixings at least 100mm away from the corner weld otherwise it may crack.
good luck.
