Can you tell me how to start a fire using flint in 3 steps?

Sure, I’d be happy to.  First you’ll need some kind of flint, which you can obtain by breaking thin slate or similar materials.  Then you’ll also need some tinder, which is a source of dry combustible material.  Finally, to interact the flint and tinder you’ll need to produce sparks using friction, usually with a similar type of material called a firesteel or striker.  With those materials and a little bit of practice, anyone can successfully start a campfire.
