\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.
