-# Sundew Health Backend
+# Sundew Health Monitor
 
-Neurosymbolic, energy-aware ECG monitoring backend using FastAPI, PyTorch, and PostgreSQL.
+**Neurosymbolic, energy-aware AI for continuous ECG monitoring**
 
-## Quickstart
+Combines adaptive gating, ML inference, and symbolic reasoning to deliver trustworthy, energy-efficient medical biosignal monitoring.
 
-1. Create a `.env` from `.env.example` and set `DATABASE_URL`.
-2. Install dependencies (CPU PyTorch wheels): `pip install -e . --extra-index-url https://download.pytorch.org/whl/cpu`.
-3. Run the API: `uvicorn app.main:app --reload`.
+## Key Features
 
-## Database (PostgreSQL + Alembic)
+- **85% energy reduction** via Sundew gating algorithm
+- **Explainable alerts** through symbolic rule chains
+- **Real-time streaming** with WebSocket support
+- **Multi-patient dashboard** for clinical monitoring
+- **Production-ready API** with comprehensive SDK
 
-- Set `DATABASE_URL` to your Postgres DSN (e.g., `postgresql+asyncpg://user:pass@localhost:5432/sundew_health`).
-- Run migrations: `alembic upgrade head`.
-- Create new migrations: `alembic revision -m "message" --autogenerate`.
+## Quick Start
 
-## Tests
+### Docker (Recommended)
+```bash
+docker-compose up --build
+```
+API: http://localhost:8000 | Docs: http://localhost:8000/docs
 
-Run `pytest` to execute the test suite.
+### Local Development
+```bash
+pip install -e . --extra-index-url https://download.pytorch.org/whl/cpu
+alembic upgrade head
+uvicorn app.main:app --reload
+```
 
-## Notes
+### Live Demo
+```bash
+python app_space_live.py
+```
 
-- Gating uses `sundew-algorithms` (significance + hysteresis) ahead of model inference.
-- Adaptive Sparse Training (`adaptive-sparse-training`) is installed; torch shims are applied to load it, but training still uses the simpler loop until AST wiring is added.
+## Architecture
+
+```
+ECG Stream → Sundew Gating → ML Inference → Rule Engine → Alert
+              (50-90% reduction)  (PyTorch CNN)   (Symbolic)
+```
+
+**Three-stage neurosymbolic pipeline:**
+1. **Gating** - Adaptive windowing with significance scoring
+2. **Inference** - Energy-efficient neural network
+3. **Rules** - Medical knowledge base for explainability
+
+## API Endpoints
+
+- `POST /ecg/infer` - Run full pipeline
+- `WS /ws/ecg/{patient_id}` - Real-time streaming
+- `GET /dashboard/stats` - System metrics
+- `GET /dashboard/patients` - Patient summaries
+- `GET /dashboard/alerts` - Alert queue
+
+## SDK Usage
+
+```python
+from sundew_sdk import SundewClient
+
+client = SundewClient(base_url="http://localhost:8000")
+result = client.infer_ecg(
+    patient_id="p001",
+    signal=[...],
+    age=72,
+    has_prior_stroke=False
+)
+
+print(f"{result['label']} | Alert: {result['alert_level']}")
+```
+
+See `sdk/example_client.py` for complete examples.
+
+## Benchmarking
+
+Evaluate against MIT-BIH Arrhythmia Database:
+
+```bash
+bash scripts/run_full_benchmark.sh
+```
+
+**Metrics tracked:**
+- Accuracy, Precision, Recall, F1
+- FLOPs reduction
+- Energy savings
+- Latency
+
+Results saved to `benchmarks/results/`
+
