My Manual · included

Build your own field manual

The most useful thing a membership gives you. No book fits your household exactly. My Manual does. Save any page on this site, recipes, charts, and whole field guides included, put them in your order, and print one manual with your name on the cover. It holds only what is relevant to you, and nothing you would skip.

Why it matters

  • It works when this site does notNo power and no signal means no website. A printed manual and an offline PDF still open, which is the whole point of writing any of this down.
  • Only your pagesThis site covers every household. Yours needs a fraction of it. Your manual holds the pages that match your water source, your climate, and your gear, so nobody digs through the rest under stress.
  • Anyone in the house can use itThe person who reads this site may not be the one home when it counts. A binder on the shelf, in your order, with a contents page, is something a spouse or a teenager can follow.
  • One current copy, not a pile of printoutsEvery page prints in the same field guide layout with a cover, a contents page, and the print date. Change a page, print again, and the old copy is easy to spot.

What to build with it

  • The house binderYour water source, your climate, your gear. Only the pages you would reach for.
  • A copy for the bug-out bag or truckA short version that travels: water, first aid, comms, and the recipes you rely on.
  • A copy for familyHand a parent or a grown kid a manual built for their house and their supplies.
