========= Rattail ========= See :doc:`/base/install/common` for more background but if you're just after the filemon service then you probably only need to do this: .. code-block:: sh pip install rattail See also :ref:`rattail-sanity-check`. Note that the above does not register the filemon service. That comes later; see :doc:`filemon/index`. You may also need to install additional Rattail packages, e.g. to integrate with your POS system. That is outside of our scope for now though.
