600 pages
"We develop foundations for abstract homotopy theory based on Grothendieck's idea of a "derivator". The theory is model-independent, and does not depend on model categories, nor on simplicial sets. It is designed to accomodate all the usual potential applications, such as e.g. enhancements for derived categories of coherent sheaves, in a way that is as close as possible to usual category theory."
He also released references [K3] and [K4]:

theory: atrocious notation, idiosyncratic terminology, and inherent
triviality of the arguments.

something that needs to be named but does not deserve a permanent name;
in these cases, we plagiarize algebraic geometry and assign words such as
“ample”, “proper” or “separated”, more-or-less randomly.
