 gprMax is currently released under the `GNU General Public License v3 or higher <http://www.gnu.org/copyleft/gpl.html>`_.
 
-gprMax is principally written in `Python <https://www.python.org>`_ 3 with performance-critical parts written in `Cython <http://cython.org>`_. It includes accelerators for CPU using `OpenMP <http://www.openmp.org>`_, CPU/GPU using `OpenCL <https://www.khronos.org/api/opencl>`_, and GPU using `NVIDIA CUDA <https://developer.nvidia.com/cuda-zone>`_. Additionally, MPI support (using `mpi4py <https://mpi4py.readthedocs.io/en/stable/>`_) enables larger scale (multi-node) simulations. There is more information about the different acceleration approaches in the :ref:`accelerators` section.
