+The SavingMechanism is the mechanism by which TiddlyWiki generates a new HTML file and stores it. It is different from the sync mechanism, which is concerned with synchronising changes to individual tiddlers back to a server (see http://tiddlywiki.com/dev/#SyncAdaptorModules for more details).
 
 The following steps are involved:
 
-# The saver mechanism uses the filter defined in $:/config/SaverFilter to specify which modified tiddlers trigger the dirty state for the wiki
+# The saver mechanism uses the filter defined in $:/config/SaverFilter to specify which modified tiddlers trigger the dirty state for the wiki. (The dirty state is reflected in the red colouring of the "save changes" button in the sidebar).
 # The ButtonWidget is used to generate a [[tm-save-wiki|WidgetMessage: tm-save-wiki]] message to trigger the save operation
 # The optional parameter for the message specifies the template that will be used for generating the HTML file, defaulting to $:/core/save/all
 #* The plugin $:/plugins/tiddlywiki/tiddlyweb in the client-server configuration replaces the default template with $:/plugins/tiddlywiki/tiddlyweb/save/offline
