Getting air in the lines somehow

Debris in the master, blocking fill port? The holes that fill the master cyl bores are tiny.
Wheel bearings adjusted correctly
And caliper mounts mounted properly?
But if its air, and bleeding is required, how much bleeding does it take to get the air?
Is it right at the bleeder, without pumping or after a few strokes of the pedal?
Using a helper, or by yourself?
And what bleeding procedure?
