After a brief review of 2d CFT basics, we introduce generalized, non-invertible symmetries in terms of explicit CFT observables. We describe how such symmetries are formalized by fusion categories and how to implement gauging of such symmetries. We also discuss the physical consequences of these mathematical structures.
