+# Preventive Maintenance Optimization
+
+VIMS instance for preventive-maintenance.
+
+## Related Article
+[/insights/the-economics-of-preventive-maintenance/](https://landvex.com/insights/the-economics-of-preventive-maintenance/)
+
+## Anomaly Classes
+- early_wear
+- component_degradation
+- environmental_stress
+- usage_anomaly
+- schedule_drift
+
+## Quick Start
+
+1. Add training images to `data/raw/`
+2. Annotate using LabelImg (YOLO format)
+3. Run preprocessing: `python src/detector.py`
+4. Train model: `python src/detector.py --train`
+5. Run inference: `python src/detector.py --predict data/test/image.jpg`
+
+## API
+
+Once deployed, access via:
+- REST: `POST /api/preventive-maintenance/predict`
+- WebSocket: `ws://host/ws/preventive-maintenance/alerts`
