**Requirements**

* Python 3.8.x or later (3.8.x, 3.9.x, 3.10.x)
* Pip (the latest versions of Python will already have this)
* Git
* PyTorch - https://pytorch.org/get-started/locally/
* Setup an alias for Python: python=python3
* Add the root folder of Lightning to the Environment Variables to PATH
* Install Z shell (zsh) (This is required for Windows to install the quickstart app)
