+🎧 Description and Use Case
+---------------------------
+This application allows for a keyboard-controlled maneuvering of your music library and the MusicBrainz database. 
+Your local library becomes "embedded" in MusicBrainz, and all metadata remains up-to-date without the need of tagging your files.
+Control playback from your terminal while browsing the vast world of music releases.
+
+🔍 Key Features
+---------------
+- [Fuzzily](https://github.com/junegunn/fzf) browse your music library
+- Treat your local library as part of the [MusicBrainz universe](https://musicbrainz.org)
+- Search the MusicBrainz database and discover music artists and releases
+- Handle metadata without touching your audio files
+- Fast and hackable application with [vim](https://www.vim.org)-like keybindings
+- Save and load playlists
+- Lyrics support
+
+🎞️ Screenshot
+-------------
+### Search Artist on MusicBrainz
+The MusicBrainz database is automatically searched after entering a query.
+In the screenshot below, the emoji 🔆 indicates that some tracks of _Mc Solaar_ are available in the local music library.
+They are played by hitting `<enter>`.
+![MusicBrainz artist search](./screenshots/search.png)
+
+### Browse Local Music Library
+Here, we fuzzily search an album of _Daft Punk._
+The LP _Random Access Memories_ can be appended to the playlist by pressing `ctrl-alt-m`.
+Alternatively, you may switch back to normal mode (`esc`) and then hit `;`.
+![Browse library](./screenshots/browse.png)
+
+### Playlist Control
+You can easily control playback and edit the playlist in the playlist view.
+![Playlist](./screenshots/playlist.png)
+
+🛠️ Requirements and Installation
+--------------------------------
+### Requirements
+This is an almost[^1] POSIX-compliant shell script with inline `awk` elements (GNU flavored, we couldn't resist) that makes calls to:
+- the command-line fuzzy finder [fzf](https://junegunn.github.io/fzf/),
+- the command-line data transferrer [curl](https://curl.se),
+- the command-line JSON processor [jq](https://jqlang.org),
+- the command-line media player [mpv](https://mpv.io), and
+- the command-line multipurpose relay [socat](http://www.dest-unreach.org/socat/).
+
+[^1]: It is written in POSIX style, but we make use of zero terminated strings.
+
+The following may improve your experience:
+- the command-line multimedia prober [ffprobe](https://ffmpeg.org/ffprobe.html) _(optional, for automatic release detection)_,
+- the command-line clipboard [xsel](http://www.kfish.org/software/xsel/) _(optional, for yanking urls)_,
+- Noto fonts _(optional, for emojis in your terminal)_.
+
+### Installation
+Run `./scripts/build.sh`, then copy `fuzic` to your preferred location, e.g., `~/.local/bin`, and make it executable.
+
+🧩 Configuration
+-----------------
+Although **no configuration** is needed, this application may be customized using environment variables.
+If the file `$XDG_CONFIG_HOME/fuzic/config` (defaults to `$HOME/.config/fuzic/config`) exists, then it will be sourced.
+You may also specify an alternative location of the configuration file with the environment variable `CONFIGFILE`.
+
+The **appearance** of the application is controlled using the environment variables defined in `src/sh/theme.sh`.
+The directory `share/theme` contains example themes.
+You may execute `CONFIGFILE=share/theme/plain.sh fuzic` to launch `fuzic` using an emojiless and colorless theme.
+
+Custom **filters** can be defined using the environment variables from `src/sh/filter.sh`.
+For instance, when you launch `F_2_LIST_ARTISTS="jazz" fuzic`, then the artist list can be queried for the word `jazz` by pressing `alt-2`.
+
+Also the **key bindings** can be reconfigured to your liking.
+For that, adjust the environment variables defined in `src/sh/keys.sh`.
+
+Finally, you can **sort** the artists according to their [sort name](https://musicbrainz.org/doc/Style/Artist/Sort_Name) by specifying `SORT_ARTIST_DEFAULT=sort-artist-sortname`,
+and the switch to alphabetical release-group sorting via `SORT_RG_DEFAULT=sort-rg-title`.
+
+
+▶️ Usage
+--------
+For a quick start, run the application and hit `alt-?` to display the available key-bindings.
+You may also open the application in one of the following predefined modes:
+```

+  --reload-database <path>      Populate database with decorated local music from <path>
+```
+
+
+🗄️ Local Music Library
+----------------------
+Instead of reading the tags from audio files, this application uses **decorations.**
+The decoration of a folder is a JSON file that stores the relevant MusicBrainz IDs of the release the folder corresponds to. 
+This assumes that complete releases are stored within separate folders.
+The application then fetches the relevant metadata, which is displayed to the user.
+Folders can be decorated using `fuzic --decorate <path>` or `fuzic --decorate-as <path> <mbid>` commands.
+The first version may be used on previously tagged files (using, e.g., [MusicBrainz Picard](https://picard.musicbrainz.org/)).
+With this command, the folder gets decorated with the MusicBrainz IDs extracted from the files.
+The latter version does not require the files to be tagged.
+Instead, it decorates the files found in that folder as the release given by the [MusicBrainz Release ID](https://musicbrainz.org/doc/MusicBrainz_Identifier) `<mbid>`.
+
+After decorating your folders, you may run `fuzic --reload-database <path>` to build your music library.
+This command searches the path specified for decorated folders.
+Once the local music library is built, it will display automatically when `fuzic` is launched.
+

+
+⌨️ Basic Keys
+-------------
+As mentioned above, you may hit `alt-?` anytime to display the possible keys.
+Note that `fuzic` allows for two modes: _normal mode_ and _insert mode._
+Similar to `vim`, keys pressed in the _normal mode_ do not directly write to the input field, but are instead bound to other actions.
+For instance, the keys `j` and `k` can be used to navigate the list down and up.
+In the insert mode, triggered using `i`, `a`, or `/`, the keys directly modify the input field. 
+
+Some central keys are `<enter>` to start playback of the selected entry, `<space>` to pause playback, and `ctrl-p` to open the currently loaded playlist.
+
+📝 Playlist Store
+-----------------
+Playlists can be saved, loaded and _shared._
+To save a playlist, simply press `ctrl-s` when viewing your playlist.
+To load a playlist, open the playlist store using `ctrl-o` while viewing your playlist.
+Alternatively, you may start `fuzic` using the command-line parameters `fuzic --load-playlist <playlist>`.
+Under the hood, a playlist is not more than a sequence of MusicBrainz IDs.
+This means that `fuzic` users may share their playlists irrespective of the audio file locations and formats.
+Possibly even more importantly, this means that you can preserve your playlist even if you reorganize your local music library:
+You can safely share your playlists with your future self.
+
+Playlists are stored under `XDG_DATA_HOME/fuzic/playlists`, which defaults to `~/.local/share/fuzic/playlists`.
+You may also define the playlist directory using the `PLAYLIST_DIRECTORY` environment variable.
+In `share/playlists` you find example playlists.
+Thus, the command `PLAYLIST_DIRECTORY=share/playlists fuzic` launches this application with access to these example playlists.
+
+📜 Lyrics
+---------
+By using the key `L` (normal mode), the lyrics of the selected track are displayed.
+The lyrics are taken from (in that order)
+1. the lyrics stored using `fuzic`, or
+2. from the `.lrc` file with the same name as the audio file, or
+3. from the audio-file tags (requires `ffprobe`), or
+4. from a custom script.
+
+To specify the custom script, you can set the `LYRICS_FETCH_CUSTOM` environment variable to point to an executable.
+The executable reads a JSON string on the standard input, and is supposed to print the lyrics (see `share/lyrics/example.sh`).
+
+You may also skip the first three sources and directly make a call to your custom script by using the key `Y` (normal mode).
+
+The key `alt-L` opens the lyrics in a new window using the `EDITOR`.
+This requires one of the following terminal emulators (`kitty`, `x-terminal-emulator`, `gnome-terminal`, `xterm`).
+If you use another terminal emulator, you may specify the environment variable `EXTERNALEDIT` to hold the string such that
+```sh
+$ExTERNALEDIT "$file"
+```
+spawns a text editor with `$file` loaded inside a terminal emulator.
+
+🧭 Planned Features
+-------------------
+The following features are planned:
+- cover art and artist images
+- genre support
+- MusicBrainz collections and favorites
+
+🌐 Information Sources
+----------------------
+Main metadata is fetched from the MusicBrainz database.
+This application also access [wikidata](https://wikidata.org), [wikipedia](https://en.wikipedia.org), and [discogs](https://www.discogs.com).
+In the future, more sources may be added.

+#
+# A format string (_FMT) contains placeholders, e.g., <<name>>. These
+# placeholders are filled with the relevant information. A placeholder may
+# occur zero times, once, or more than once. There are two types of
+# placeholders: strings and items. A placeholder of type string comes with a
+# variable containing a `printf` expression (_FMT_placeholder). This `printf`
+# expression may be used to additionally modify the string passed. If the
+# string passed is empty, then each corresponding placeholder is replaced
+# with the empty string, i.e., the `printf` expression is bypassed. A
+# placeholder of the alternative type (item) comes with a series of variables
+# that encode constants to be used (_FMT_placeholder_XYZ).
+#
+# The items in the format string may be separated with "\t". This will induce
+# a proper representation (using `column`). By default, all fields but the
+# first are left aligned, and the first field is right aligned. This can be
+# changed by setting the appropriate FMT_RIGHTALIGN variable. If that
+# variable is empty, then the first field is right aligned. This means that
+# at least one field must be right aligned.

+
+# General workings of format strings
+#
+# A format string (_FMT) contains placeholders, e.g., <<name>>. These
+# placeholders are filled with the relevant information. A placeholder may
+# occur zero times, once, or more than once. There are two types of
+# placeholders: strings and items. A placeholder of type string comes with a
+# variable containing a `printf` expression (_FMT_placeholder). This `printf`
+# expression may be used to additionally modify the string passed. If the
+# string passed is empty, then each corresponding placeholder is replaced
+# with the empty string, i.e., the `printf` expression is bypassed. A
+# placeholder of the alternative type (item) comes with a series of variables
+# that encode constants to be used (_FMT_placeholder_XYZ).
+#
+# The items in the format string may be separated with "\t". This will induce
+# a proper representation (using `column`). By default, all fields but the
+# first are left aligned, and the first field is right aligned. This can be
+# changed by setting the appropriate FMT_RIGHTALIGN variable. If that
+# variable is empty, then the first field is right aligned. This means that
+# at least one field must be right aligned.

+  # General workings of format strings
+  #
+  # A format string (_FMT) contains placeholders, e.g., <<name>>. These
+  # placeholders are filled with the relevant information. A placeholder may
+  # occur zero times, once, or more than once. There are two types of
+  # placeholders: strings and items. A placeholder of type string comes with a
+  # variable containing a `printf` expression (_FMT_placeholder). This `printf`
+  # expression may be used to additionally modify the string passed. If the
+  # string passed is empty, then each corresponding placeholder is replaced
+  # with the empty string, i.e., the `printf` expression is bypassed. A
+  # placeholder of the alternative type (item) comes with a series of variables
+  # that encode constants to be used (_FMT_placeholder_XYZ).
+  #
+  # The items in the format string may be separated with "\t". This will induce
+  # a proper representation (using `column`). By default, all fields but the
+  # first are left aligned, and the first field is right aligned. This can be
+  # changed by setting the appropriate FMT_RIGHTALIGN variable. If that
+  # variable is empty, then the first field is right aligned. This means that
+  # at least one field must be right aligned.
