The free PDF is 40 pages. It was written in 2017. It covers all the basics (water, food, medications, sanitation, staying warm, and defense) but it also has sections on how not to become emotionally overwhelmed and how to maintain morale. New materials include a section on feeding infants; a section on protecting yourself from radiation; how to build an evaporation “refrigerator”(for diabetics); and a handy table of contents.
There was one mistake that needs to be changed in the next version. It suggested using wasp spray as a form of defense, since the spray shoots 20 feet. This is not recommended any more. It could be harmful. Instead, an option is purchasing a pepper spray that shoots several feet.

While some preppers know all this stuff, I think that most people will find this just the right amount of information to get all the essentials worked out. You don’t have to plow through a whole book. You don’t even have to buy a book. I think that most people will be delighted with this free resource.
