 ## Credits
 
 This module wouldn't be possible without the amazing work of MichMich in MagicMirror and balloob, the developer of the pyChromecast library for Python. Also, huge kudos to python-shell developers, which allowed me to exchange data between the Python script and node.
-Mention to paviro as well, as I used his module as a "template" to know the basics of python-shell. It would have been so much difficult to use MagicMirror alongside Python script without his help.
