Faced with the recent experimental discoveries of pentaquarks and tetraquarks, one would like to establish whether these states arise directly from the fundamental theory of strong interactions - QCD. I will present how the exotic and conventional hadrons are investigated with ab-initio lattice QCD simulations. The approach will be illustrated with recent lattice results on the charmonium-like states Zc and X(3872), conventional resonances, bound states and pentaquarks.
