+\DescribeMacro{\savebetweenoverlays}
+The |page| and |equation| counters are not incremented between overlays. Other
+counters can be saved between overlays, too, by means of the following command:
+\begin{quote}
+|\savebetweenoverlays{|\meta{counter name}|}|
+\end{quote}
+Typically, this command would be used in the preamble.
+
 \section{Known limitations}
 
 The |\alert|, |\visible|, and |\only| commands must not contain verbatim
 commands or environments. They may be used in the content of the |alltt|
 environment, though.
 
+\section{Dependencies}
+
+The \textsf{overlays} package requires the following packages: \textsf{color},
+\textsf{environ}, and \textsf{pgffor} (part of \textsf{pgf}).

 \section{Credits}
 
 The code of the \textsf{overlays} package is inspired by Matthias Meister's
 \textsf{present} package.
 
 In addition, it uses an algorithm by Martin Scharrer for testing numbers in
-numerical ranges (cf. \url{http://tex.stackexchange.com/q/19000/}).
+numerical ranges (cf. \url{http://tex.stackexchange.com/q/19000}).
 
-The code for processing overlays with verbatim content is taken from the
-\textsf{texpower} package, which in turn took it from Till Tantau's
-\textsf{beamer} package.
+The code for saving counters between overlays as well as for overlays with
+verbatim content is taken from the \textsf{texpower} package, which in turn is
+based on Till Tantau's \textsf{beamer} package.
