-The \tikzducks package is a latex package for ducks to be used in \texttt{tikz} pictures. This project is a continuation of an answer at TeX.Stackexchange (\url{https://tex.stackexchange.com/a/347458/36296}).

+This project is a continuation of an answer at TeX.Stackexchange: \href{tex.stackexchange.com/a/347458/36296}{How can we draw a duck?}.
 
-This package is work in progress (and will probably never be really finished as there is an infinite amount of things which could be added), therefore I would be happy to hear your feedback and ideas how to improve the package.

+First of all \href{https://tex.stackexchange.com/users/101651/carlatex}{CarLaTeX} for pointing out the overwhelming need of having a \tikzducks package and \href{https://tex.stackexchange.com/users/3094/paulo-cereda}{Paulo Cereda} for his contagious enthusiasm for ducks (\emph{Quack!}). Many other users contributed to this package (in random order): \href{https://tex.stackexchange.com/users/4427/egreg}{egreg} helped to implement the \lstinline|\tikzset{}| interface which makes it much easier to adjust the properties of the ducks to fit the user needs, \href{https://tex.stackexchange.com/users/51022/symbol-1}{Symbol 1}  solved a few problems with default key values, \href{https://tex.stackexchange.com/users/2388/ulrike-fischer}{Ulrike Fischer} gave valuable \TikZ advices and last but not least my thanks go to \href{https://tex.stackexchange.com/users/5763/martin-schr%c3%b6der}{Martin Schr\"oder} for his feedback to the code review.
 
-\subsection{Acknowledgements}
+The ducks mostly consist of basic geometric shapes drawn in \TikZ. Some of the more complex shapes (e.g.\ the different hair styles) are first drawn in \texttt{inkscape}\footnote{\url{inkscape.org}} and then exported to \TikZ paths using the \texttt{SVG to TikZ/PGF} extension\footnote{\url{github.com/kjellmf/svg2tikz}}
+
+\subsection{Dependencies}
+
+The \tikzducks package loads the packages \lstinline|xcolor| and \TikZ, both without any options. If you require one of these packages to be loaded with some option, please consider loading it yourself before the \tikzducks package or use, e.g.
+
+\vskip0.5em
+\begin{lstlisting}[morekeywords={xcolor,svgnames}]
+	\PassOptionsToPackage{svgnames}{xcolor}
+\end{lstlisting}
+It also uses the \lstinline|\usetikzlibrary{patterns}|.
