The document provides instructions for performing a proper badminton long serve. It describes the serve in four parts: 1) the stance, with feet shoulder-width apart and sideways to the net; 2) the ready position, with elbow and racket high; 3) striking the shuttlecock with a pendulum swing and weight shift; 4) finishing with the racket overhead and facing the net. The performance expectation is to serve the shuttlecock deep into the opposing court 75% of the time using proper form.
