Summarize this article:

Begin blowing softly through the bundle while gently squeezing the tinder around the coal. As more tinder catches, you might have to turn and/or reshape it to keep the ember spreading into more and more of the tinder. Blowing will provide more oxygen to stoke the fire and transfer the energy from the coal to the tinder bundle. Continue blowing and gently squeezing with the tinder bundle until you get actual flames. Put it on the ground where you want your fire. Keep blowing if you need to keep the flames going. Add the toothpick size sticks on top of the bundle, then the pencil sized sticks, followed by increasingly bigger items until you have your campfire.  If you have prepared a teepee-type fire put the burning tinder bundle into the center. Keep blowing slowly and steadily to help spread the fire.

Summary:
Blow through the tinder bundle. Build your fire.
