That paper looks pedagogical indeed :)

As for myself I've mainly used #BartoszMilewski 's #CategoryTheory for #Programmers: « There is a free pdf version of this #book with nicer typesetting available for download. You may order a hard-cover version with color illustrations at #Blurb. Or you may watch me #teaching this material to a live audience. »

He has also written a few articles for the #SchoolOfHaskell, including a few on #Yoneda: https://www.schoolofhaskell.com/user/bartosz
