-Sections of audio are known as _regions_ in Ardour. A Region can be an entire
-sound file or a portion of it. Here you will learn how to import audio files
-from the hard drive of your computer so they can be used in your Ardour session.
-
-To import an audio file into your session, you will use the _Add Existing Media_
- dialog. Use the shortcut **Ctrl+I** to get to this window, or alternatively go
-to the `Session > Import` menu).
-
-On the left side of this dialog you will see a file browser which allows you to
-search your hard drive for appropriate sound files to add (preferably, start
-with a common file format, such as WAV or AIFF).
+You can reuse existing audio and MIDI files by adding them as regions on
+existing or new tracks. To do so, press the **Ctrl+I** shortcut or go to the
+`Session > Import` menu to open the _Add Existing Media_ dialog, pick a file of interest, and import it.

-At the lower left corner there is a menu which indicates how these files will
-be added. _Add files… as new tracks_ will import audio files and place them on
-a newly created track. _Add files… to source list_ will simply import audio
-files into the Sources list, without creating any new tracks. Choose this
-option now, as we don't want Ardour to create any tracks at this point. Make
-sure the _Mapping_ options says _one region per file_.
+Some settings are the same for audio and MIDI, some are format-specific.

+## Playing existing files
+
+Before you import a file, it's a good idea to make sure it's the right one. On
+the right side of the _Add Existing Media_ dialog you will see a section
+allowing you to inspect the properties of the file you selected. Here you will
+see the name, number of channels, sample rate, format and length of the sound
+file, along with any tags you have chosen to add to the file.
+
+The **Play** button allows you to preview the file. You can also select
+**Auto-play** if you would like to hear a sound file immediately as soon as
+you click on it in the file browser (without having to push the **Play**
+button).
+
+For MIDI files, you can select a virtual instrument that will be used to play
+the selected MIDI file, although you won't be able to select a particular
+synth patch.
+
+## Choosing Tracks and Insertion Point
+
+There are some common scenarios for importing media files: importing multiple
+audio files as new tracks and inserting them into the session start, importing
+multiple audio files to the list of of available sources for later use,
+importing one MIDI file into an existing track at the playhead position, etc.
+So there are two important options here: where to insert a region generally
+(which track, if at all), and which point of the timeline to insert to.
+
+The _Add files …_ drop-down list if where you choose the former, and the
+_Insert at_ drop-down list is where you choose the latter.
+
+## Inserting to Sources list
+
+Let's start with the scenario where you import some audio files into the list of sources.
