  YubiKey Manager is a Qt5 application written in QML that uses the plugin PyOtherSide to enable 
  the backend logic to be written in Python 3. The python library yubikey-manager is needed to communicate with the YubiKey,
  and is included as a submodule in the repository. It can also be installed through pip and some other package managers.
