Shaving cream can be used both with and without shaving brush!
With brush: Place a thumbnail large dollop of shaving cream on top of your wet shaving brush. Lather up with the brush directly on your face. Add more water if necessary.
Without brush: Take a thumbnail large dollop of shaving cream and massage into a lather between wet fingers. Apply with fingertips directly on your face. With moistened fingertips and gentle circular motion, continue to massage the cream into a rich lather. Add more water if necessary.
