\title{{\bf Category Theory to Yoneda's Lemma}}
\author{Greg O'Keefe}
\maketitle

This development proves Yoneda's lemma and aims to be 
readable by humans.  It only defines what is needed for 
the lemma: categories, functors and natural transformations.
Limits, adjunctions and other important concepts are not 
included.

There is no explanation or discussion in this document.  See
\cite{fcat4cats} for this and a survey of category theory
formalisations.
