VisualEditor comes "out of the box" with a basic stand-alone demonstration across a variety of example inputs. You can access this at
demos/ve/desktop.html. This is merely a demonstration, and does not allow you to load or save content to a platform.

If you wish to integrate VisualEditor into a new platform – maybe Wordpress, Drupal or some other Web-based CMS – we'd love to help. You can ask on the talk page of this page, by e-mail to wikitext-l, or on IRC on #mediawiki-visualeditor on freenode.
