========

Even though :tirreno:`Tirreno` is a system utilizing numerous
sophisticated techniques inside, on the outside it is designed to be an
approachable solution. Accordingly, in this user guide, we make an
effort to introduce as little special terminology and concepts as
possible without compromising the guide’s applicability and
comprehensiveness for users of the system.

Following is a list of terms that may come in handy when acquainting
oneself with :tirreno:`Tirreno`. The terms are listed in the order
corresponding to the :ref:`workflow of the system <system-workflow>`.

    Trust Score
