The basic Coq-code libraries that set up identity types and the resulting homotopy type theory are at

A slightly more human readable version is collected as a single pdf in
A collection of all this code equipped with html-functionality that does display also the proofs (which otherwise only display when the code is loaded into a Coq-system) is at
A further translation of these proofs into ordinary text is in
