What part does lady macbeth play in macbeths plan to kill the king

Lady Macbeth's plan includes having King Duncan stabbed to death with daggers and framing the guards (who will be drugged and unable to react to the murder) in his room by rubbing them with the king's blood. She will signal Macbeth when it is time for him to go to the King's quarters to do the deed.
