+### Usage-GUI
+
+The GUI script uses [Qt for Python](https://wiki.qt.io/Qt_for_Python) ([PySide2](https://pypi.org/project/PySide2/)). So you can make sure you have that package installed by running:  
+```bash
+pip3 install --user PySide2
+```
+After that you can just run the script like so:
+```bash
+python3 ./RetroUFO_GUI.py
+```
+
+You can then just click the `Grab Cores` button at the bottom and then you should be all set.

+
+If you would like to grab cores for a different platform or architecture you can override which supported cores it grabs.

+
+If you have your core directory set somewhere special you can override where the cores extract to.
