Upcoming Large-Scale Structure surveys will become the next leading sources of cosmological information. It is thus very important to have a precise understanding of how cosmology influences the distribution of matter in the Universe. The Effective Field Theory of Large-Scale Structure (EFTofLSS) is a consistent framework to predict the clustering of matter on large scales, that only recently has first been applied to extract cosmological information. In this talk, we will introduce the EFTofLSS, and see how well it fits the data. We will also see how the EFTofLSS even allow us to analytically model very complex and non-linear dynamics such as baryonic processes, in a finite set of measurable parameters.
