+The xmpp platform allows you to deliver notifications from Home Assistant to a Jabber (XMPP) account.
+
+```yaml
+# Example configuration.yaml entry
+notify:
+    platform: xmpp
+    sender: YOUR_JID
+    password: YOUR_JABBER_ACCOUNT_PASSWORD
+    recipient: YOUR_RECIPIENT
+```
+
+All Jabber IDs (JID) must include the domain. Make sure that the password matches the account provided as sender. 
+
+To use notifications, please see the [getting started with automation page]({{site_root}}/components/automation.html).
