Instead, start with the material on actual Markov processes, and then work backwards through the foundational chapters as needed. (The flow-chart at the end of the book, indicating which results depend on which previous ones, is very helpful for this.) There is a wealth of fascinating material here, of profound importance for statistics and for physics, since both rely crucially on extracting nearly-deterministic behavior from large-scale Markov processes, which is a key theme of these results.
