   Slighly adjusted the lead-in of this page: Added a line on what the book is actually about, and moved the line advertizing how great this is to after that.

   Added the line:

   The approach is echoed in Riehl & Verity 13 with Cat enhanced to the homotopy 2-category of (∞,1)-categories.

   Also touched some wording further below (“is very difficult to read” $\mapsto$ “may be difficult to read”)

   and added the missing cross-link with John Gray (1)

   Finally, I made “formal category theory” a redirect to this page (this would deserve to point to a dedicated page, but as long as that doesn’t exit, it’s good to have it redirect here)
