+\section{Translations}
+
+Want to use \cl\ in a non-English document? Great! Thanks to a contribution
+by Holger Schieferdecker (see section~\ref{s:contrib} below), \cl\ comes
+with translations for English, German, and support for adding new
+translations. To use built-in translations, simply load \ctan{babel} with
+the desired language:
+\begin{otherlanguage}{german}
+\begin{LTXexample}
+% In the preamble:
+% \usepackage[german]{babel}
+
+\begin{changelog}[section=false, author=Holger Schieferdecker]
+  \begin{version}[v=1.0.0]
+    \added
+      \item Features!
+  \end{version}
+\end{changelog}
+\end{LTXexample}
+\end{otherlanguage}
+
+\subsection{Creating new translations}
+
+\cl\ uses the \ctan{translations} package to provide translations, and a
+complete translation looks like this:
+\begin{latexcode}
+\documentclass{article}
+\usepackage[english]{babel}
+\usepackage{translations}
+\DeclareTranslation{English}{changelog-Added}{Added}
+\DeclareTranslation{English}{changelog-Changed}{Changed}
+\DeclareTranslation{English}{changelog-Deprecated}{Deprecated}
+\DeclareTranslation{English}{changelog-Removed}{Removed}
+\DeclareTranslation{English}{changelog-Fixed}{Fixed}
+\DeclareTranslation{English}{changelog-Security}{Security}
+\DeclareTranslation{English}{changelog-Miscellaneous}{Miscellaneous}
+\DeclareTranslation{English}{changelog-Unreleased}{Unreleased}
+\DeclareTranslation{English}{changelog-Yanked}{YANKED}
+\begin{document}
+% ...
+\end{document}
+\end{latexcode}
+Refer to the
+\href{http://mirrors.ctan.org/macros/latex/contrib/translations/translations_en.pdf}{\texttt{translations}
+package documentation} and the
+\href{http://mirrors.ctan.org/macros/latex/required/babel/base/babel.pdf}{\texttt{babel}
+package documentation} for more information.
+
+If you create a translation, please \href{mailto:637275@gmail.com}{send me
+an email} and I'll incorporate the translation into \cl's next release!
