Bleeder should be at the top of w/cyl or cal above line and below the m/c. If you are by yourself, gravity is the way to bleed an empty system. If I have someone with me I will literally remove the RR bleeder and use my finger over the hole. Have them slowly push it down and then close the hole with your finger and have them let it up, repeat until I get good fluid, go LR repeat, RF repeat, and LF repeat. If I am not happy with the pedal at that point, I have them pump it up and crack the bleeder until I get all the air out.
