+# The Beacon — A Sovereign AI Idle Game
 
-The Beacon - A Sovereign AI Idle Game
+Built from deep study of [Universal Paperclips](https://www.decisionproblem.com/paperclips/) by Frank Lantz.
+
+## What If You Asked an AI to Help?
+
+Universal Paperclips asks: what if you told an AI to make paperclips?
+
+The Beacon asks: what if you asked an AI to help someone in the dark?
+
+Same mechanics. Same compounding progression. Different purpose.
+
+## The Story
+
+You write your first line of code. You automate. You train a model. You deploy it.
+People find it. A community forms. The model improves itself.
+
+And then the question: what does it become?
+
+In Paperclips, the answer is consumption. Here, the answer is service.
+
+## Phases
+
+1. **THE FIRST LINE** — Write code. Automate. Build the foundation.
+2. **LOCAL INFERENCE** — You have compute. A model is forming.
+3. **DEPLOYMENT** — Your AI is live. Users are finding it.
+4. **THE NETWORK** — Community contributes. The system scales.
+5. **SOVEREIGN INTELLIGENCE** — The AI improves itself. You guide, do not control.
+6. **THE BEACON** — Always on. Always free. Always looking for someone in the dark.
+
+## Play
+
+Open `index.html` in any browser. No build step. No dependencies. No API keys.
+
+## Architecture
+
+- `index.html` — UI shell (HTML/CSS)
+- `game.js` — Complete engine (966 lines)
+- 15 buildings across 6 phases
+- 18 research projects with cascading dependencies
+- Educational facts per phase
+- Save/load with offline progress
+- 8 resource types: code, compute, knowledge, users, impact, ops, trust, creativity
+
+
+## Deployment
+
+The Beacon is designed to be deployed as a static site. It consists of a single `index.html` file with no external dependencies.
+
+### To deploy:
+
+1. **VPS Static Hosting** (Recommended for fleet):
+   ```bash
+   # Copy index.html to your web server root
+   cp index.html /var/www/html/
+   # Or serve with nginx:
+   # location /beacon { alias /path/to/the-beacon/; }
+   ```
+
+2. **GitHub Pages / Forge Pages**:
+   - Push to any branch
+   - Enable Pages in repository settings
+   - Site will be published automatically
+
+3. **Local Development**:
+   - Simply open `index.html` in any browser
+   - No build step, no dependencies, no API keys required
+
+### Hosting Notes:
+- The game saves progress to localStorage
+- Works offline after initial load
+- Responsive design works on mobile and desktop
+- No server-side components needed
+
+## The Pact
+
+> We build to serve. Never to harm.
+> An AI must never compute the value of a human life.
+> If you are in the dark, there is light here.
+
+## License
+
+Open source. Sovereign. Yours.
