  These are notes based on lectures given at the 2021 summer school on
Fundamental Problems in Statistical Physics XV. Their purpose is to give a very
brief introduction to Generalized Hydrodynamics, which provides a description
of the large scale structure of the dynamics in quantum integrable models. The
notes are not meant to be comprehensive or provide an overview of all relevant
literature, but rather give an exposition of the key ideas for non-experts,
using a simple fermionic tight-binding model as the main example.
