+<p>
+	Meterbridge is a compact view of all meters in a session. It is designed
+	to assist for large recording sessions, particularly live recording where
+	the amount of mics is too large to get a good overview of the entire session
+	in either the <kbd class="window">Mixer</kbd> or the
+	<kbd class="window">Recorder</kbd> window.
+</p>

+
+<p>
+	By default, the Meterbridge window displays a meter per each track with
+	the track's name at the bottom and allows resetting the meter's peak
+	as well as arm a track for recording.
+</p>
+
+<p>
+	Each meter has a right-click menu to select the type of the meter.
+	Just like in the mixer channel view, tracks and regular audio busses default
+	to <kbd class="option">Peak (+6&nbsp;dBFS)</kbd> and the master bus defaults
+	to <kbd class="option">K14 (RMS)</kbd>. It's also possible to set the same
+	meter type to all same-type tracks.
+</p>	
+<p>
+	Additionally, it's possible to select the height of the track name panel
+	by right-clicking above it and selecting one of the options going from
+	Short to Venti (which is a coffee cup size reference).
+</p>
+
+<p>
+	Just like in the usual mixer channel view,
+	the <kbd class="button">Arm for Recording</kbd> button has a right-click
+	menu to enable rec-safe mode to avoid accidental recording to a track
+	of choice.
+</p>
+
+<p>
+	The set of readily available controls can be customized per each session
+	on the <kbd class="window">Meterbridge</kbd> page of the
+	<kbd class="window">Session Properties</kbd> dialog.
+</p>
+
+<p>
+	Additional controls include:
+</p>
+
+<ul>
+	<li>Mute button</li>
+	<li>Solo button</li>
+	<li>Monitor buttons</li>
+	<li>Fader as a gain knob</li>
+</ul>
+
+<p>
+	It's also possible to toggle visibility of MIDI tracks, busses,
+	and the master bus.
