  We discuss how primordial (e.g. inflationary) non-Gaussianity in the
cosmological perturbations is left imprinted in the Large-Scale Structure of
the universe. Our findings show that the information on the primordial
non-Gaussianity set on super-Hubble scales flows into Post-Newtonian terms,
leaving an observable imprint in the Large-Scale Structure. Future
high-precision measurements of the statistics of the dark matter density and
peculiar velocity fields will allow to pin down the primordial non-Gaussianity,
thus representing a tool complementary to studies of the Cosmic Microwave
Background anisotropies.
