I review the appearence of integrable structures in the formulation of exactnonperturbative solutions to $4d$ supersymmetric quantum gauge theories.Various examples of ${\cal N}\geq 2$ SUSY Yang-Mills nonperturbative solutionsare adequately described in terms of the (deformations of the) finite-gapsolutions to integrable models: through the generating differential and the$\tau$-function. One of the basic definitions of generating differential isdiscussed and its role in the theory of integrable systems is demonstrated.
