 * Plugins from the official plugin library are replaced with references to those plugins in the `tiddlywiki.info` file
 * Custom plugins are unpacked into their own folder

+The following options are supported:
+
+* ''filter'': a filter expression that defines the tiddlers to include in the output.
+* ''explodePlugins'': defaults to "yes"
+** ''yes'' will "explode" plugins into separate tiddler files and save them to the plugin directory within the wiki folder
+** ''no'' will suppress exploding plugins into their constituent tiddler files. It will save the plugin as a single JSON tiddler in the tiddlers folder
+
+Note that both ''explodePlugins'' options will produce wiki folders that build the exact same original wiki. The difference lies in how plugins are represented in the wiki folder.
+
 A common usage is to convert a TiddlyWiki HTML file into a wiki folder:

 ```
 tiddlywiki --load ./mywiki.html --savewikifolder ./mywikifolder
 ```
+
+Save the plugin to the tiddlers directory of the target wiki folder:
