  This survey gives a self-contained introduction to q-analogues of multiple
zeta values (qMZVs). For this, we consider most common models of qMZVs in a
unified setup going back to Bachmann and K\"uhn, such as a related
quasi-shuffle product each. Also, we give distinguished translations between
several models. As another unified approach to qMZVs, we introduce the concept
of marked partitions.
