+# This script converts markdown into html, to be used with vimwiki's
+# "customwiki2html" option.  Experiment with the two proposed methods by 
+# commenting / uncommenting the relevant lines below.
+#
+#   NEW!  An alternative converter was developed by Jason6Anderson, and can
+#   be located at http://code.google.com/p/vimwiki/issues/detail?id=384
+#
+#
+# To use this script, you must have the Discount converter installed.
+#
+#   http://www.pell.portland.or.us/~orc/Code/discount/
+#
+# To verify your installation, check that the commands markdown and mkd2text,
+# are on your path.
+#
+# Also verify that this file is executable.
+#
+# Then, in your .vimrc file, set:
+#
+#   g:vimwiki_customwiki2html=$HOME.'/.vim/autoload/vimwiki/customwiki2html.sh'
+#
+# On your next restart, Vimwiki will run this script instead of using the
+# internal wiki2html converter.
