 * 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 same 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:
+
+```
+tiddlywiki --load ./mywiki.html --savewikifolder ./mywikifolder explodePlugins=no

+!Introduction
+
+The <<.op :then>> filter run prefix is used to replace the result of all previous filter runs with its output.
+
+If the result of all previous runs is an empty list, the <<.op :then>> prefixed filter run is not evaluated.
+
+If the output of a <<.op :then>> prefixed filter run is itself an empty list, the result of all previous filter runs is passed through unaltered.
+
+<<.tip "Note that a list with a single empty string item is not an empty list.">>
+
+
+!! <<.op :then>> run prefix versus the <<.olink then>> operator
+
+The major difference between the <<.op then>> operator and a <<.op :then>> prefixed filter run is that the operator will replace //each item// of the input [[Title List]] with its parameter while <<.op :then>> will replace the //whole input list// with the result of its run.
