    I have slightly touched the wording, formatting and hyperlinking.

    Notice that we have a dedicated entry fiber type.

    On a trivia note: I find the nested subscripts on equality signs make an otherwise transparent account look like symbol soup – and they are not even necessary for parsing. My suggestion would be to delete them all.

  3. Added section on the type of identity functions and a proof that it is contractible.
