<human>:  I want to start a fire with flint but haven't done it before. How do I do it?
<bot>: To start a fire with flint, you'll need to create a spark. Start by striking a rock in a downward motion onto the piece of flint. The spark created should light a clump of tinder. To make sure it does, hold the spark near tinder and blow gently to help create an ember that will eventually ignite the tinder. Once you have a flame, add dry kindling to help the fire grow. Make sure to keep it shielded from the wind and add fuel gradually to maintain the blaze.
