 If you haven't already, install NEURON. Detailed instructions for special cases are available `here <../install/install_instructions.html>`_, but in brief, you'll probably want to install Python (there are many options; `Anaconda <https://www.anaconda.com/>`_ is one such option). On Linux and macOS, you can then install NEURON by typing ``pip install neuron``. On Windows, use the latest NEURON installer from `our GitHub site <https://github.com/neuronsimulator/nrn/releases>`_. For parallel simulation, you will also want to install a version of MPI.
