-Distributed Quick Start
------------------------
-
-1. Import and initialize Ray by appending the following to your example script.
-
-.. code-block:: python
-
-    # Append to top of your script
-    import ray
-    import argparse
-
-    parser = argparse.ArgumentParser()
-    parser.add_argument("--ray-address")
-    args = parser.parse_args()
-    ray.init(address=args.ray_address)
-
-Alternatively, download a full example script here: :download:`mnist_pytorch.py <../../python/ray/tune/examples/mnist_pytorch.py>`
-
-2. Download the following example Ray cluster configuration as ``tune-local-default.yaml`` and replace the appropriate fields:
-
-.. literalinclude:: ../../python/ray/tune/examples/tune-local-default.yaml
-   :language: yaml
-
-Alternatively, download it here: :download:`tune-local-default.yaml <../../python/ray/tune/examples/tune-local-default.yaml>`. See `Ray cluster docs here <autoscaling.html>`_.
-
-3. Run ``ray submit`` like the following.
-
-.. code-block:: bash
-
-    ray submit tune-local-default.yaml mnist_pytorch.py --args="--ray-address=localhost:6379" --start
-
-This will start Ray on all of your machines and run a distributed hyperparameter search across them.
-
-To summarize, here are the full set of commands:
-
-.. code-block:: bash
-
-    wget https://raw.githubusercontent.com/ray-project/ray/master/python/ray/tune/examples/mnist_pytorch.py
-    wget https://raw.githubusercontent.com/ray-project/ray/master/python/ray/tune/tune-local-default.yaml
-    ray submit tune-local-default.yaml mnist_pytorch.py --args="--ray-address=localhost:6379" --start
