 This package is work in progress, 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/tikzlings}, including a bug tracker -- please make constructive use of it! 
+If you seek any other assistance (not bug reports/feature requests), I suggest asking a question at \url{topanswers.xyz/tex}.
 A more stable package version can be found on \CTAN (\url{https://www.ctan.org/pkg/tikzlings}) and is included in both \miktex and \texlive as \tikzlings.
