+To hide tab bar, when there is a single tab, the following resource need to be
+set to true::
+
+    URxvt.tabbedalt.autohide: true
+
+By default tab bar would be visible even with only one tab. Note, that it will
+be visible regardless of this option, when ``new-button`` is set. So to make
+that option work, you'll need to also disable new-button.
