This is an introduction to the blackfold effective worldvolume theory for the dynamics of black branes, as well as its use as an approximate method for the construction of new black hole solutions. We also explain how the theory is useful for the analysis of dynamical, non-stationary situations, in particular of the Gregory-Laflamme instability of black branes.
