Well, I don't think people need instructions on how to set fire to "a thing" as you stated. I'm not quite sure that's really relevant here though, I'm not instructing people on how to set fire at all. I would think a brain dead monkey could figure that out. I'm merely providing instructions on how to build a fire that is from my own personal experience is very safe and smothers itself once it's burned out.
