+# TrustedAir Dust Index Predictor
+
+This is a placeholder model created by TrustedAir Labs to simulate air quality index scoring based on particulate matter readings (PM2.5).
+
+## Example Usage
+```python
+from trustedair_dust_index import predict_dust_index
+predict_dust_index(pm25=42)
+```
+
+## Intended Use
+This model is for demonstration purposes only and is not a certified air quality metric or diagnostic tool.
