+
+### Instructions:
+
+
+Download the [WMD source](http://wmd-editor.com/downloads/wmd-1.0.1.zip).  In that zip file you'll
+find a few example html files, a readme and `wmd` directory.  Move the `wmd` directory into the
+ikiwiki `underlays` directory.  You should now have an `underlays/wmd/wmd.js` file as well as 
+some other javascript files and an images directory in the same place.
+
+> So, I wonder if I should add a copy of the WMD source to ikiwiki, or rely
+> on the user or distribution providing it. It does not seem to be packaged
+> for Debian yet. --[[Joey]] 
+
+Note that the WMD plugin does **not** handle directives.  For this reason the normal `preview` button
+remains.  Some CSS to clean up the display of the live WMD preview would be good.
+
+> Can you elucidate the CSS comment -- or will it be obvious what you mean
+> when I try it? Is it what's needed for the live preview? --[[Joey]]
+
+Install the following patch and plugin file.  Then enable the 'wmd' plugin.
