+## .Exiftool_config
+a configuration file that adds some SD-related tags allowing exiftool to edit them. It can read the tags but cannot edit them until they are defined.
+### related:
+* https://exiftool.org/
+* https://github.com/hvdwolf/jExifToolGUI/releases
+
+## workping.py
+A CLI script for adding a workflow to a PNG file. Requres Pillow module (PIL). It updates the image file, make a backup if you want extra safety.
+python workping.py --image "/path/to/image.png" --workflow "/path/to/workflow.json"
