 ```

+To ensure that the "save changes" button saves a full, standalone wiki, it is also necessary to set the tiddler $:/config/SaveWikiButton/Template to contain `$:/core/save/all-external-js`.

+The provided edition `server-external-js` contains all the configuration necessary to use the external ~JavaScript template.

 !! Background
 
-TiddlyWiki in the single file configuration ordinarily packs everything into a single file: your data, and the JavaScript, CSS and HTML comprising TiddlyWiki itself. This lack of dependencies is usually very convenient: it means that it is impossible for the parts of a TiddlyWiki to become separated, and enormously improves the chances of it still functioning in the future.
+TiddlyWiki in the single file configuration ordinarily packs everything into a single file: your data, and the ~JavaScript, CSS and HTML comprising TiddlyWiki itself. This lack of dependencies is usually very convenient: it means that it is impossible for the parts of a TiddlyWiki to become separated, and enormously improves the chances of it still functioning in the future.
 
 However, there is some inefficiency in this arrangement because the core code is repeatedly loaded and saved every time the content of the wiki is saved. This inefficiency is partially ameliorated when working in the client server configuration because once the wiki is loaded by the browser the synchronisation process only transmits individual tiddlers back and forth to the server.
