+# The user interface of this application is composed out of the following
+# views.
+# - VIEW_ARTIST: Show all release group of an artist
+# - VIEW_RELEASEGROUP: Show all releases within a release group
+# - VIEW_RELEASE: Show track list of release
+# - VIEW_SEARCH_ARTIST: Interface to search artists on MusicBrainz
+# - VIEW_SEARCH_ALBUM: Interface to search albums (release groups) on MusicBrainz
+# - VIEW_LIST_ARTISTS: Presentation of all artists in the local database
+# - VIEW_LIST_ALBUMS: Presentation of all albums (release groups) in the local database
+# - VIEW_SELECT_ARTIST: Interface for the user to select an artist
+# - VIEW_PLAYLIST: View on the currently loaded playlist and playlist manipulation
+# - VIEW_QUIT: Exiting view, to terminate the application
+#
+# All views but the last three are handled within a single fzf instance. The
+# views VIEW_SELECT_ARTIST, and VIEW_PLAYLIST run each in a separate fzf
+# instance. The last view (VIEW_QUIT) does nothing but terminate the
+# application.
+#
+# The fzf instance comprising VIEW_ARTIST - VIEW_LIST_ALBUMS is always in one
+# of two modes: normale mode (MODE_NORMAL) or insert mode (MODE_INSERT). Both
+# modes come with different key bindings. It is only in the insert mode that
+# the query string can be written.
+#
+# All views and modes are referred to by the following constants. The values
+# are arbitrary but distinct.
