+Application Mode
+----------------
+
+dupeGuru had three main modes: Standard, Music and Picture.
+
+Standard is for any type of files. This makes this mode the most polyvalent, but it lacks
+specialized features other modes have.
+
+Music mode scans only music files, but it supports tags comparison and its results window has many
+audio-related informational columns.
+
+Picture mode scans only pictures, but its contents scan type is a powerful fuzzy matcher that can
+find pictures that are similar without being exactly the same.
+
+Choosing an application mode not only changes available scan types in the selector below, but also
+changes available options in the preferences panel. Thus, if you want to fine tune your scan, be
+sure to open the preferences panel **after** you've selected the application mode.
+
+Scan Type
+---------
+
+This selector determines the type of the scan we'll do. See :doc:`scan` for details about scan
+types.

 An alternate way to add folders to the list is to drag them in the list.

-iPhoto and Aperture libraries
------------------------------
-
-dupeGuru Picture Edition supports iPhoto and Aperture, which means that it knows how to read these
-libraries and how to communicate with iPhoto and Aperture to remove photos from them. To use this
-feature, use the special "Add iPhoto Library" and "Add Aperture Library" buttons in the menu that
-pops up when you click the "+" button. This will then add a special folder for those libraries.
-
-When duplicates are deleted (sent to trash) from an iPhoto library, it's sent to iPhoto's
-trash.
-
-When duplicates are deleted (sent to trash) from an Aperture library, it unfortunately can't
-send it directly to trash, but it creates a special project called "dupeGuru Trash" in Aperture
-and send all photos in there. You can then send this project to the trash manually.
-
-iTunes library
---------------
-
-dupeGuru Music Edition supports iTunes, which means that it knows how to read its libraries and how
-to communicate with iTunes to remove songs from it. To use this feature, use the special
-"Add iTunes Library" button in the menu that pops up when you click the "+" button. This will
-then add a special folder for those libraries.
-
-When duplicates are deleted from an iTunes library, it's sent to the system trash, like a
-normal file, but it's also removed from iTunes, thus avoiding ending up with missing entries
-(entries with the "!" logo next to them).
