+Displays real-time air quality data with EPA color coding.
 Shows AQI index (US EPA or European scale) and pollutant breakdown for PM2.5, PM10, O3, NO2, CO, and SO2.
 
+## Data Sources
+
+| Source | Type | API Key | AQI Scales |
+|--------|------|---------|------------|
+| **Open-Meteo** (default) | Forecasting (CAMS atmospheric models) | Not required | US EPA, European |
+| **AQICN** | Real monitoring station data | Free token required | US EPA only |
+
+- **Open-Meteo** uses Copernicus CAMS atmospheric models at 11-40km resolution. No API key needed, but values are forecasted estimates.
+- **AQICN** provides real-time data from the nearest EPA monitoring station. Requires a free API token from [aqicn.org/data-platform/token](https://aqicn.org/data-platform/token). Shows the station name in the location pill.
