Milk frothing is extremely easy and quick. Simply heat the milk to your preferred temperature (not boiling, the temperature should be about 60-65 degrees). Then froth the heated milk, pumping the plunger knob vigorously several times. Once you get the desired effect, which is velvety, fluffy froth, pour it directly onto your brewed coffee. Fill the frother up to 1/3 of its capacity, as milk volume increases.
