Probably it would be good to learn at least basics of AMScd. Do you happen to know link to some document explaining basics of this package.
$$\require{AMScd}\begin{CD}
A @>f>> B\\
@VVV @VVV\\
RA @>>{Rf}> RB
\end{CD}
$$
$$\require{AMScd}\begin{CD}
A @>f>> B\\
@V{r_A}VV @VV{r_B}V\\
RA @>>{Rf}> RB
\end{CD}
