* BEAT familiarity: This guide assumes you are somewhat familiar with what BEAT is and how it works. Please see :ref:`beat-system` and refer to it if you come across an unfamiliar BEAT term or concept.
* A BEAT **prefix**: All the building blocks of BEAT is stored in a directory typically named *prefix* (see :ref:`prefix`). For the purpose of this tutorial we provide this folder. Please download the prefix folder in this `git repository <https://gitlab.idiap.ch/beat/beat.tutorial.prefix>`_ . Run any BEAT commands relating to the prefix in the top-level folder of it, next to the prefix folder.
* To simplify code examples, we will be using `Bob`_, a free signal-processing and machine learning toolbox originally developed by the Biometrics group at `Idiap`_ Research Institute, Switzerland. Please add the Conda channel for ``bob`` to the Conda environment with BEAT packages are installed and then install the packages needed for this tutorial.
