Twisted graphene bilayers define tunable Moiré structures with unique properties, including superconductivity and other broken symmetry phases. The electronic bands show unusual topological features, and very narrow bandwidths. The main features of these bands, as well as the nature and role of the leading interactions are discussed. Emphasis is made on the interplay between electrostatic interactions and superconductivity.
