Abstract
An overview of Chiral Perturbation Theory calculations in
the mesonic sector at the two Loop level is given.
Discussed in some detail are the partially quenched case
relevant for lattice QCD, the general fitting procedures
and $\pi\pi$,$\pi K$ scattering as well as the
determination of $V_{us}$ and $K_{\ell3}$ decays.
