Different tutorials on Yambo can be found online:

Linear response in realtime.
In this tutorial you will learn how to perform realtime simulation to get the dielectric constant of bulk materials. Results will be compared with standard linear response theory.
Second Harmonic Generation (SHG) in AlAs
In this tutorial we will calculate
second harmonic generation (SHG) in AlAs
Correlation effects in SHG
In this tutorial we will introduce correlation effects in the SHG spectra. Different approaches will be considered.
Third Harmonic Generation (THG) in Silicon.
In this tutorial we will calculate the THG response of bulk silicon.
Realtime BSE.
This tutorial explains how to run a realtime BetheSalpeter calculation.
Dealing with large systems.
This tutorial explains how Lumen is parallelized and how you can calculate nonlinear response in complex and large systems.
