+# Script: system-nvidia-smi
+
+A script that shows the NVIDIA GPU utilization.
+
+
+## Dependencies
+
+* `nvidia-smi`
+
+
+## Configuration
+
+There are several `--query-gpu=` values. Use nvidia-smi `--help-query-gpu` for a complete list and description. The most notable are `fan.speed`, `memory.used`, `memory.total`, `driver_version`, `power.draw`, `pstate`.
+
+If you don't need custom labelling use instead:
+`nvidia-smi --query-gpu=utilization.gpu --format=csv,noheader`
+
+
+## Module
+
+```ini
+[module/system-nvidia-smi]
+type = custom/script
+exec = ~/polybar-scripts/system-nvidia-smi.sh
+interval = 10
+```
