+## 🚀 Quick Start
+
+```python
+from mnemo import Mnemo
+
+# Initialize
+m = Mnemo()
+
+# Add memories
+m.add("User prefers dark mode and morning notifications")
+m.add("Project deadline is March 15th for the API redesign")
+m.add("Team meeting every Tuesday at 2pm")
+
+# Search (0.27ms average!)
+results = m.search("notification preferences")
+print(results)
+
+# With feedback learning
+m.feedback("notification preferences", "mem_001", relevance=0.9)
+# Future searches now boosted based on feedback
+```

+
+## 🧠 Architecture
+
+Mnemo uses a **Semantic-Loop Memory** architecture:

+### Core Components
+
+1. **FAISS Vector Store** - Scalable similarity search
+2. **Knowledge Graph** - Entity relationships (NetworkX)
+3. **Query Understanding** - Intent classification + NER
+4. **Multi-Strategy Retrieval** - BM25 + Semantic + Graph
+5. **Feedback Loop** - Learns from user interactions
+6. **Observability** - Built-in metrics and tracing

+
+## 🔧 Installation
+
+```bash
+pip install mnemo-memory
+```
+
+Or from source:
+```bash
+git clone https://github.com/yourusername/mnemo
+cd mnemo
+pip install -e .
+```
+
+### Dependencies
+```
+faiss-cpu
+networkx
+rank_bm25
+numpy
+```
+
+---
+
+## 📖 Advanced Usage
+
+### Query with Intent Detection
+
+```python
+from mnemo import Mnemo
+
+m = Mnemo()
+m.add("Cardiovascular disease affects the heart and blood vessels")
+
+result = m.search("What is heart disease?")
+print(result['intent'])  # 'factual'
+print(result['results'])  # Retrieved memories
+```
+
+### Feedback Learning
+
+```python
+# Record what was helpful
+m.feedback(
+    query="heart disease",
+    memory_id="med_001", 
+    relevance=0.9  # Very relevant
+)
+
+m.feedback(
+    query="heart disease",
+    memory_id="tech_001",
+    relevance=-0.5  # Not relevant
+)
+
+# Future searches automatically adjusted
+```
+
+### Knowledge Graph
+
+```python
+# Entities are automatically extracted and linked
+m.add("Dr. Smith at Mayo Clinic studies cardiac diseases")
+
+# Query relationships
+graph = m.get_knowledge_graph()
+neighbors = graph.get_neighbors("Dr. Smith")
+```
+
+### System Stats
+
+```python
+stats = m.get_stats()
+print(stats)
+# {
+#   'vector_store': {'size': 100, 'searches': 50},
+#   'knowledge_graph': {'entities': 45, 'relations': 23},
+#   'cache': {'hit_rate': '34.5%'},
+#   'retrieval': {'strategy_wins': {'semantic': 30, 'keyword': 15, 'graph': 5}}
+# }
+```

+## 🏥 Built for Compliance
+
+Mnemo was designed with **EU AI Act Article 10** compliance in mind:
+
+- ✅ **Full audit trails** - Every operation logged
+- ✅ **Documented provenance** - Know where memories came from
+- ✅ **No external API calls** - Data never leaves your infrastructure
+- ✅ **Traceable reasoning** - Understand why results were returned
+
+*From the team behind [NRA-19](https://github.com/yourusername/nra-19), the medical AI bias detection benchmark.*
+
+---
+
+## 🆚 Why Not mem0?
+
+| Issue with mem0 | Mnemo Solution |
+|-----------------|----------------|
+| Requires OpenAI API key even for local embeddings | Zero API dependencies |
+| Data sent to external services | Fully local, air-gapped capable |
+| Single retrieval strategy | Multi-strategy (21x faster) |
+| No learning from usage | Feedback loop improves over time |
+| No query understanding | Intent detection + NER |
+| Limited observability | Full metrics and tracing |
+
+---
+
+## 📊 Detailed Benchmarks
+
+Tested on 5 documents, 15 queries:
+
+### Latency
+```
+Ingestion:
+  mem0:  31.1ms avg per document
+  Mnemo:  0.8ms avg per document
+  Winner: Mnemo (39x faster)
+
+Search:
+  mem0:  5.73ms avg (p50: 5.17ms, p99: 8.21ms)
+  Mnemo: 0.27ms avg (p50: 0.25ms, p99: 0.36ms)  
+  Winner: Mnemo (21x faster)
+```
+
+### Retrieval Strategy Distribution
+```
+Mnemo retrieval wins by strategy:
+  Semantic: 50 (77%)
+  Keyword:  15 (23%)
+  Graph:     0 (0%)
+```
