I aim to give some review of how generalised geometries provide a natural
framework for describing supersymmetric string backgrounds. In particular I
will focus on a rewriting of type II supergravity in terms of generalised
structures. Hitchin functions appear naturally along with generalised
extensions of the Gukov-Vafa-Witten superpotential.
