 Building into an exe (on Windows):
 - pipx install pyinstaller  (note: you can try without pipx, but this didn't work for me)
 - Run:
-  - CMD:  `pyinstaller --onefile --name install-betterfox install.py && move %cd%\dist\install-betterfox.exe %cd% && del install-betterfox.spec && rmdir /S /Q build && rmdir dist`

   - BASH: `pyinstaller --onefile --name install-betterfox install.py && && mv dist/install-betterfox.exe . && rm install-betterfox.spec && rm -rf ./build/ && rmdir dist`
   (Sorry, didn't want to add a .gitignore solely for the install script)
 - Done!
