+[Converse](https://conversejs.org) is a web based [XMPP/Jabber](https://xmpp.org) chat client.
 
-It enables you to add chat functionality to your website, independent of
-any specific backend. You will however need an XMPP server to connect
-to, either your own, or a public one.
+You can either use it as a webchat app, or you can integrate it into your own website.
+
+It''s 100% client-side JavaScript, HTML and CSS and the only backend required
+is a modern XMPP server.
