This is how you bleed brakes with a helper. Begin with the right rear, then left rear, right front, and left front. The hose must be a tight fit around each bleeder with the end submerged at all times. Have your helper do a slow pedal depression (halfway) and watch closely. Flush until there is solid fluid flow from the hose. If you're starting with an empty system, be prepared for a lot of air bubbles.
