+Be sure to first [setup your environment](#environment-setup).
+Without arguments, they will run the standard demo arguments used as an example elsewhere

 ## QuickStart Docker
 :star: To try out TTS inference with VoiceCraft, you can also use docker. Thank [@ubergarm](https://github.com/ubergarm) and [@jayc88](https://github.com/jay-c88) for making this happen.
