Some very brief remarks on derivateurs are in Bertrand Toen's habilitation thesis on pages 12-14 and 27-29, available [here][1]. They mainly emphasize how derivateurs are sort of a 2-truncated homotopy theory of homotopy theories - nothing to learn derivateur-language from, but maybe a nice addition to the general picture.
