Hello
=====

Two ways to add a hyperlink:

* `PyG Documentation <https://pytorch-geometric.readthedocs.io/en/latest/index.html>`_

* Get the latest news at `CNN`_.

Let's go to other sections in this doc:

#. go to :doc:`/Others/Others0`.

#. go to :doc:`Functional Map of the World </Data/Data0>`.

#. go to :ref:`anotherdataset <dataset>`.



.. _CNN: http://cnn.com/

Here is a code example:

.. code-block:: python

    print ('hello world')
