We give a brief introduction to flavour physics. The first part covers the
flavour structure of the Standard Model, how the Kobayashi-Maskawa mechanism is
tested and provides examples of searches for new physics using flavour
observables, such as meson mixing and rare decays. In the second part we give a
brief overview of the recent flavour anomalies and how the Higgs can act as a
new flavour probe.Comment: 32 pages, 22 figures, the write-up is a combination of lectures given
at ESHEP 2018, SSI 2018 and the US Belle II summer schools, Fig. 1 corrected,
several typographical errors fixe
