Welcome to athena's documentation!
===================================

**athena** is a Fortran library for implementing neural networks.

The code is provided freely available under the `MIT License <https://opensource.org/licenses/MIT>`_.

The library is aimed at providing tools for building and training neural networks in Fortran;
the focus is on convolutional layers, message passing layers, and physics informed neural networks, but other layers are also provided.

The athena library, once installed, can be imported into a Fortran program with the statement:

.. code-block:: fortran

   use athena

The list of supported layers can be found :ref:`here <layers>`.

An example of how to use the library is shown below:


.. container:: tight-toc

   .. toctree::
      :maxdepth: 1
