A better option is this book or pdf file if in a shtf situation. https://pic8.co/sh/wfHBvy.jpg Idk if it would violate any laws or TOS to post these type of PDFs from my collection but it is one of my favorites. I imagine just posting the table of contents would get me on some type of watch list, so I don't want to go into any further detail. Sorry for being so vague about it, but it's definitely worth a read through.
