To expand on Percusse's comment, you can start with this code:

\documentclass{article}
\usepackage{amsmath,tikz-cd}
\begin{document}
\begin{equation*}
\begin{tikzcd}[column sep=2cm]
A\arrow[r,"\text{inclusion}"] \arrow[rd, swap,"\varphi"] & F(A) \arrow[d,"\Phi"] \\
                                                         & M
\end{tikzcd}
\end{equation*}
\end{document}

giving:

    \arrow[rd,swap,"\varphi"] will move the phi to the other side. Also \arrow[rd,"\varphi"'] would work, but it's less readable.
