+## LibreHardwareMonitor Exporter
+
+Minimal Prometheus exporter using `LibreHardwareMonitorLib` to expose basic hardware metrics (CPU, GPU, memory, motherboard, network, storage).
+
+### Run
+
+- Build and run the console app.
+- Endpoint: `http://localhost:9646/metrics` (set `PORT` env var to change port)
+- Some sensors may require administrator privileges.
+
+### Prometheus scrape config
+
+```yaml
+scrape_configs:
+  - job_name: lhm_exporter
+    static_configs:
+      - targets: ['localhost:9646']
+```
+
+### Metrics
+
+Exports gauges like:
+- `lhm_temperature_celsius`
+- `lhm_load_percent`
+- `lhm_clock_mhz`
+- `lhm_power_watts`
+- `lhm_fan_rpm`
+- `lhm_voltage_volts`
+
+Each metric includes `hardware` and `sensor` labels.
