     4. Press CTRL + S to save.
     5. Reload open pages to see it run.
 
+## Using the *local* card.py
+
+> I now have a local python3 script you can run to get the same effect as using you're grease monkey script (This way you have a CLI to use)
+
+1. Clone this repo
+2. Make a python virtual environment (See [venv](https://docs.python.org/3/library/venv.html))
+3. (Activate virtual environment) `pip install pyperclip` (See [pyperclip](https://pypi.org/project/pyperclip/) for additional setup it may require, *Under Linux*)
+4. Run `./card.py` (This should display help)
