 Introduction to PyTorch - YouTube Series
 ========================================
 
-Authors: 
-`Brad Heintz <https://github.com/fbbradheintz>`_
-
-This tutorial follows along with the `PyTorch Beginner Series <https://www.youtube.com/playlist?list=PL_lsbAsL_o2CTlGHgMxNrKhzP97BaG9ZN>`_ on YouTube.
-
-`This tutorial assumes a basic familiarity with Python and Deep Learning concepts.`

-Running the Tutorial Code
--------------------------
-You can run this tutorial in a couple of ways:
+This page has been moved.
 
-- **In the cloud**: This is the easiest way to get started! Each section has a Colab link at the top, which opens a notebook with the code in a fully-hosted environment. Pro tip: Use Colab with a GPU runtime to speed up operations *Runtime > Change runtime type > GPU*
-- **Locally**: This option requires you to setup PyTorch and torchvision first on your local machine (`installation instructions <https://pytorch.org/get-started/locally/>`_). Download the notebook or copy the code into your favorite IDE.
