+# Usage
+
+For detailed command-line arguments, run:
+
+```bash
+./bin/sd-cli -h
+```
+
+For direct image repair or automatic post-generation YOLOv8 detection followed by cropped inpainting, see
+[ADetailer](../../docs/adetailer.md).
+
+Metadata mode inspects PNG/JPEG container metadata without loading any model:
+
+```bash
+./bin/sd-cli -M metadata --image ./output.png
+./bin/sd-cli -M metadata --image ./output.jpg --metadata-format json
+./bin/sd-cli -M metadata --image ./output.png --metadata-raw
+./bin/sd-cli -M metadata --image ./output.png --metadata-all
+```
