+# TNFR Wiki - Quick Reference
+
+![Wiki Graphics Preview](wiki_graphics_preview.png)
+
+## 📖 Wiki Pages
+
+Start here: **[Home](Home.md)**
+
+### Main Pages
+
+| Page | Description | Content |
+|------|-------------|---------|
+| **[Home](Home.md)** | Main landing page | Overview, installation, quick example, navigation |
+| **[Getting Started](Getting-Started.md)** | First steps with TNFR | Installation, tutorials, workflow, troubleshooting |
+| **[Core Concepts](Core-Concepts.md)** | Theory and fundamentals | NFRs, nodal equation, operators, metrics, fractality |
+| **[Examples](Examples.md)** | Real-world applications | Biology, social, AI, distributed systems, finance, physics |
+
+## 🎨 Visual Assets (5 Graphics)
+
+All graphics are high-resolution (300 DPI) and located in the `images/` directory:
+
+1. **network_resonance.png** - NFR nodes in a resonant network
+2. **structural_operators.png** - The 13 canonical operators
+3. **paradigm_comparison.png** - Traditional vs TNFR paradigms
+4. **coherence_metrics.png** - Metrics evolution over time (C(t), Si, ΔNFR, νf)
+5. **nodal_equation.png** - The canonical nodal equation explained
+
+## 📊 Statistics
+
+- **Total lines**: ~1,700 lines of markdown
+- **Total size**: ~1.8 MB (including graphics)
+- **Code examples**: 30+ executable Python examples
+- **Visualizations**: 5 custom-generated graphics
+- **Use cases**: 10+ domain-specific applications
+
+## 🚀 Quick Start
+
+```python
+from tnfr.sdk import TNFRNetwork
+
+# Create, activate, and measure a network
+network = TNFRNetwork("hello_world")
+results = (network
+    .add_nodes(10)
+    .connect_nodes(0.3, "random")
+    .apply_sequence("basic_activation", repeat=3)
+    .measure())
+
+print(results.summary())
+```
+
+## 🔧 Regenerating Graphics
+
+```bash
+cd wiki
+python generate_graphics.py
+```
+
+## 📝 Using This Wiki
+
+### For GitHub Wiki
+
+1. Navigate to repository's Wiki tab
+2. Create pages: Home, Getting-Started, Core-Concepts, Examples
+3. Copy content from .md files
+4. Upload images where referenced
+
+### For Documentation Site
+
+Add to `mkdocs.yml`:
+
+```yaml
+nav:
+  - Wiki:
+      - Home: wiki/Home.md
+      - Getting Started: wiki/Getting-Started.md
+      - Core Concepts: wiki/Core-Concepts.md
+      - Examples: wiki/Examples.md
+```
+
+### For Local Reading
+
+View markdown files directly on GitHub or with any markdown viewer.
+
+## 🎯 Design Principles
+
+- ✅ **English only** per TNFR guidelines
+- ✅ **Visual-first** approach with lots of diagrams
+- ✅ **Paradigm-aligned** with strict TNFR concepts
+- ✅ **Beginner-friendly** progressive complexity
+- ✅ **Code-heavy** with executable examples
+- ✅ **Self-contained** pages work independently
+
+## 🔗 External Resources
