+==== polymake configuration ====
+The default configuration used by the jupyter kernel is the one in ''$HOME/.polymake''. If you need to reconfigure a rules file, it is easiest to reconfigure it outside of jupyter. Note that the configuration is only saved to ''$HOME/.polymake'' once polymake gets closed using ''exit;''.
+Advance users can use a different configuration folder in the following way:
+<code>
+alias jupymake="env POLYMAKE_USER_DIR=$HOME/.polymake-jupyter jupyter notebook --notebook-dir=$HOME/jupyter-notebooks"
