+### Template extraction
+> :warning: **Please note:** <br>
+> This tool uses the legacy format for datasets.<br>
+> Images are sorted using folders, instead of by name
+
+1. Images should have four standard Aruco markers clearly visible
+2. Run the template extraction tool with an input directory as argument
+```sh
+$ python ./src/experiments/template_extraction/script.py ./dataset
+```
+3. The script generates new folders, ending with `_out`
+4. The paths to any failed images are saved in `skipped.txt`
