+
+The SavingMechanism is the mechanism by which TiddlyWiki generates a new HTML file and stores it. It is different from the SyncMechanism, which is concerned with synchronising changes to individual tiddlers back to a server.
+
+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 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 $:/core/save/all
+# The template includes a variable assignment that specifies a filter to select the tiddlers that should be included in the saved file. It then transcludes the main page template `$:/core/templates/tiddlywiki5.html`
+# The [[tm-save-wiki|WidgetMessage: tm-save-wiki]] handler renders the template to generate the HTML file
+# The message handler chooses the highest priority "saver" module that can handle saving the file
+#* See http://tiddlywiki.com/dev/#Saver for more details
