Abstract: We review lattice results related to pion, kaon, TeX - and TeX -meson physics with the aim of making them easily accessible to the particle-physics community. More specifically, we report on the determination of the light-quark masses, the form factor TeX , arising in semileptonic TeX transition at zero momentum transfer, as well as the decay-constant ratio TeX of decay constants and its consequences for the CKM matrix elements TeX and TeX . Furthermore, we describe the results obtained on the lattice for some of the low-energy constants of TeX and TeX Chiral Perturbation Theory and review the determination of the TeX parameter of neutral kaon mixing. The inclusion of heavy-quark quantities significantly expands the FLAG scope with respect to the previous review. Therefore, we focus here on TeX - and TeX -meson decay constants, form factors, and mixing parameters, since these are most relevant for the determination of CKM matrix elements and the global CKM unitarity-triangle fit. In addition we review the status of lattice determinations of the strong coupling constant TeX .
