Requirements
============

This project uses ``uv``, which you can install by running the following command:

.. code-block:: shell

    curl -LsSf https://astral.sh/uv/install.sh | sh

With uv ready, run ``uv sync --all-extras``. This will install the correct python version and dependencies, the package **with all extras**.
