Hello! How you bleed your brake system depends on the vehicle you have. Some vehicles are bleed in a certain pattern. Dodge 4x4 pickups for example are bleed in an X pattern. Google the bleed procedure for your vehicle to see. Most older vehicles are bleed by starting with the farthest wheel from the master cylinder and working back. While it is possible to bleed the master cylinder and then the wheels, if you did not replace the master cylinder it is not required, however, it will take much time and patience to get out all the air. If you have a pressure or vacuum bleed system to use this will make the job much easier. If not you will need an assistant to pump the brake peddle and hold it while you crack the bleeder. Be sure to recover and dispose of the old brake fluid, it is hydraulic fluid. Good luck!
