+PulseAudio
+----------
+If you find standard MPD volume control useless, you may instead configure
+*nncmpp* to show and control the volume of any PulseAudio sink MPD is currently
+connected to.
+
+This feature may be enabled with the *settings.pulseaudio* configuration option,
+as in the snippet above.  To replace the default volume control bindings, use:
+
+....
+normal = {
+  "M-PageUp" = "pulse-volume-up"
+  "M-PageDown" = "pulse-volume-down"
+}
+....
+
+The respective actions may also be invoked from the help tab directly.
+
+For this to work, *nncmpp* needs to access the right PulseAudio daemon--in case
+your setup is unusual, consult the list of environment variables in
+*pulseaudio*(1).  MPD-compatibles are currently unsupported.
