-Because different users will want to use Ardour for different tasks, the
-way time is measured in the application can be changed.
+Once you import some audio files to Ardour, play them back and start
+familiarizing yourself with the user interface, you might want finetuning
+various parts of the user interface for your needs. The timeline settings are
+one of the obvious options there, because what you want to see on the timeline
+largely depends on the kind of material you work on.
 
-Users creating audio plays, documentaries, reportages or soundscapes may wish to use
-**Minutes** and **Seconds**, for example, while those recording bands or
-producing electronic music will most likely use **Bars** and **Beats**.
-Video producers will find a frames-per-second **Timecode** handy, while
-those wishing for extreme precision may even want to use **Samples**.
-All of these can be viewed in Ardour and used as a means to organize
-your regions and edits.

-Primary and Secondary Clocks
-----------------------------
+Let's talk about setting up clocks, snapping, and timeline rulers.
 
-There are two clocks near the top of the **Editor Window** which can
-display the time in a number of formats: *Timecode*, *Bars:Beats*,
-*Minutes:Seconds* and *Samples*. Right-click to change the format of
-each of the two clocks.

-These are called the transport clocks. The left one is the primary
-transport clock and the right one is the secondary transport clock. The
-advantage of having two transport clocks is that you see the playhead
-position in two different time units without having to change any
-settings.

-To the right of these two clocks you see the "mini-timeline", also called "navigation timeline". Check the Ardour Manual for more informaion on [clocks](http://manual.ardour.org/ardours-interface/using-ardour-clock-displays/) and the [mini-timeline](https://manual.ardour.org/ardours-interface/mini-timeline/).
+If you never need the second clock, you can disable it entirely. Go to 
+`Edit > Preferences > Appearance > Toolbar` and disable the _Display Secondary
+Clock_ checkbox.
 
-Snap Modes
-----------
+To the right of these two clocks you can see the _mini-timeline_, also called
+_Navigation Timeline_. It's a convenient way to be reminded of cues and location
+markers, especially when you are in the _Recorder_ window where the timeline
+doesn't have those rulers.
 
-The **Snap Mode** menus are found just below the Clocks to the right.
-They control the amount **Quantization** of the time grid, i.e., the
-amount of "snap" an audio **Region** has to the type of grid you have
-chosen.

+Check the Ardour manual for more information on
+[clocks](http://manual.ardour.org/ardours-interface/using-ardour-clock-displays/)
+and the
+[mini-timeline](https://manual.ardour.org/ardours-interface/mini-timeline/).
+
+## Snap Modes
+
+Snapping settings are located just below the clocks to the right. They control
+the _quantization_ of the time grid, i.e., to which units the timeline grid is
+divided and to what extent audio regions and MIDI notes get snapped when
+snapping is enabled. E.g. you can snap to whole seconds when you drag an audio
+region around or you could snap to 1/16 of a bar when creating or editing MIDI
+notes.
+
+There is one global switch, _Snap_, and then a drop-down list of grid
+quantization presets: _Bar_, _1/4 note_, _1/8 note_ etc., _Triplets_,
+_Timecode_, _Minutes and Seconds_, _CD frames_, and more.

-When *No Grid* is selected, Regions may be moved freely around within
-the Tracks. When *Grid* is selected, Regions will "snap" to the nearest
-**Grid Point**. When *Magnetic* is selected, Regions can be moved freely
-but will "snap" to a Grid Point when they are moved very close to one.
+When _No Grid_ quantization preset is selected, there is no grid displayed on
+the tracks/busses canvas. In that case, with snapping off, nothing will snap.
+And with snapping enabled, regions and notes will only snap to location markers.
 
-The middle **Units** menu is used to select what the Grid Points will
-be, such as Beats, Bars, Marks, Minutes, Seconds, various aspects of the
-SMPTE Timecode, or the edges of Regions. 
+## Timeline
 
-Timeline
---------
+The _timeline_ is located below the snapping settings, just above the main
+canvas. By right-clicking on the timeline labels (i.e., right-click on the
+left-side area where the words "Timecode, Bar:Beats, Meter" etc are displayed),
+you can set the check boxes to show or hide the different types of time
+information.
