Abstract
We explain, in a non technical way, several general methods for constructing semi-universal deformations, especially by Kuranshi maps. Moreover, we give (standard) criteria of universality and smoothness of the semi-universal deformation, discuss the existence of operations on the base germ and describe intrinsically the Massey products.
