Computing masses of hadrons is a fundamental goal of lattice QCD. In this framework, we necessarily work in a finite volume and with a nonzero lattice spacing. While we can extrapolate to the continuum, an infinite volume extrapolation is too computationally expensive. In this talk, I will present the Lüscher formalism which relates the (low-lying) finite-volume spectrum of a system to its infinite-volume scattering amplitude. To do this, it uses the finite-volume quantization condition. I will outline the derivation of this condition and will show its application in the simple case of s-wave scattering.
