[johnportelance]

does this only work on apple machines? i tried to run the api command on my desktop npm update and it does not recognize the command? so can I do this app on my desktop PC or not? before I continue lol. or is there a way to run the cmd from the file, because I don't know how to do that if so? Or from the command line in windows 10 what command from the api directory would I use?
