 \label{intro}
 
 Rubber ducks can be made of latex, but can they also be made with \LaTeX? Yes! The \tikzducks package is a \LaTeX{} package for rubber ducks to be used in \TikZ pictures. 
-This project is a continuation of \href{tex.stackexchange.com/a/347458/36296}{How can we draw a duck?}.
+This project is a continuation of \href{https://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. 
-The head version of the source code can be found on \url{github.com/samcarter/tikzducks}, including a bug tracker -- please make constructive use of it! A more stable package version can be found on \CTAN (\url{www.ctan.org/pkg/tikzducks}) and is included in both \miktex and \texlive as \tikzducks. If you seek any other assistance (not bug reports/feature requests), I suggest asking a question at \url{topanswers.xyz/tex}.

-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} (\url{https://inkscape.org}) and then exported to \TikZ paths using the \texttt{SVG to TikZ/PGF} extension (\url{https://github.com/kjellmf/svg2tikz}).
