your guide USB

On a computer or USB stick

  1. Plug in a USB stick. Any will do — Lite needs ~5 MB, Standard about 600 MB of space.
  2. Download a package above. It saves as a single .zip file (check your Downloads folder).
  3. Unzip it. Double-click the .zip — Windows and Mac open it for you. You get a last-light-survival-guide folder.
  4. Drag that whole folder onto your USB stick. Wait for it to finish copying — that's it, it's saved.
  5. Open it anywhere. Plug the stick into any computer, open the folder, and double-click index.html. It opens in the browser and works fully offline, forever.

💡 Keep a copy on the stick and your computer. To give it to someone, just copy the folder across — no installing anything.

🔒 Comfortable with a terminal? sh make-usb.sh /Volumes/MYUSB (inside the unzipped folder) copies the guide and re-reads every byte on the stick against SHA-256 hashes — so a flaky drive is caught now, not the day you need it.

home screen ⚡ Last Light

On your phone or tablet (like an app)

Save the guide to your home screen so it opens like an app and works offline. This gives you the full written guide, all 28 sections, tools, skills and search — no internet needed.

📱 iPhone / iPad — Safari
  1. Open bunkerbot.co.uk in Safari (you may be here now).
  2. Tap the Share button (the square with an ↑).
  3. Scroll down and tap Add to Home Screen.
  4. Tap Add — an app icon appears. Open it anytime, offline.
🤖 Android — Chrome
  1. Open bunkerbot.co.uk in Chrome.
  2. Tap the ⋮ menu (top-right).
  3. Tap Add to Home screen (or Install app).
  4. Confirm — the icon appears on your home screen and works offline.

The offline AI assistant and the bundled PDF books need a computer to run — the phone install gives you the written guide and search offline, which is the core of it.

Where to keep it

Knowledge only helps if you can reach it. Keep at least two copies in different places, so a lost phone or a dead laptop never loses the guide.

Your computerThe working copy you use day to day.
A USB stickYour grab-and-go backup — keep it with your kit or bug-out bag.
Your phoneInstalled to the home screen — always in your pocket, offline.

🛡️ For real resilience, add a copy on a second USB kept somewhere separate — a car, a relative's house, a waterproof tin. It's just files; copy it as many times as you like.

💡 Want the offline AI, maps, and "install as an app" too? Double-clicking index.html gives you the written guide, but browsers block those three features when a page is opened as a plain file. One click fixes it: run start.command (or double-click it in Finder) — it starts everything and opens the guide in your browser, unlocked. Verify your download first with sh verify.sh.

Optional extras

Set it up with one command (recommended)

Installs the offline AI, auto-picks the right model for your machine (down to old/low-RAM hardware — no need to read a table), and can serve the whole guide to every device on your network. Run these from inside the unzipped folder, in order:

Skip this and Bunker Bot still works — it searches the bundled books and shows you the right page, it just won't generate a written answer.

1
Check the download is intact: sh verify.sh
2
Run the script for your OS:
macOS — also serves the guide to your network on bootsh mac-setup.sh
Linux / Raspberry Pi — same, plus fetches the guide itselfsh pi-setup.sh
Windowspowershell -ExecutionPolicy Bypass -File windows-setup.ps1
3
Open index.html, click Bunker Bot — it should already be answering.

Safe to re-run any time — every step skips what's already done. Prefer to do it by hand, or want a llamafile instead of Ollama? See below.

＋ Add the offline AI manually (optional)

Bunker Bot can run a real AI model fully offline. The easiest way is a llamafile — a single file that is the model and the server, no install, works on Windows/Mac/Linux. It's a separate download (1–3 GB) so the packages above stay small.

1
Download a llamafile — start with Llama-3.2-3B-Instruct (~2.3 GB; or the 1B, ~0.9 GB, for older hardware) from Mozilla's llamafile project or Hugging Face.
2
Make it runnable and start it:chmod +x *.llamafile && ./your-model.llamafile --server --nobrowser
3
Open the guide, click Bunker Bot, choose the Llamafile mode — it connects automatically. Ask away, fully offline.

⚠️ Small models can be wrong, especially on medical questions — Bunker Bot leans on the bundled books to stay grounded, but always verify anything critical.

⌨ Prefer the terminal? (no browser)

The Standard package includes bunkerbot.py — the whole assistant in one zero-dependency Python file, ideal for a headless Raspberry Pi or over SSH. Same book-cited answers, no browser:

python3 bunkerbot.py "how do I stop heavy bleeding"

Auto-detects Ollama or a llamafile; with no model it drops to a fast search-only lookup over the library. Python 3 only — nothing to install.

＋ Add Wikipedia, Gutenberg & world maps

Too big to bundle, but one click away: the Expansion Library links every offline knowledge base — all of Wikipedia and Project Gutenberg via Kiwix, and offline maps of anywhere on Earth. mac-setup.sh/pi-setup.sh above already offer to download the two biggest ones (Gutenberg + full Wikipedia) automatically — this page is for picking specific smaller archives instead.

This project is free and always will be. Hosting, maps, and the reference library cost a little to keep online — if it's helped you, chipping in keeps it alive and ad-free for the next person.
100% optional. The guide is yours either way.
