+# Jukebox
+
+The jukebox mode allow playing audio files on the hardware of the machine
+running Supysonic, using regular clients that support it as a remote control.
+
+The daemon must be running in order to be able to use the jukebox mode. So be
+sure to start the `supysonic-daemon` command and keep it running. A basic
+_systemd_ service file can be found at the root of the project folder.
+
+## Setting the player program
+
+Jukebox mode in _Supysonic_ works through the use of third-party command-line
+programs. _Supysonic_ isn't bundled with such programs, and you are left to
+choose which one you want to use. The chosen program should be able to play a
+single audio file from a path specified on its command-line.
+
+The configuration is done in the `[daemon]` section of the
+[configuration file](configuration.md), with the `jukebox_command` variable.
+This variable should include the following fields:
+
+- `%path`: absolute path of the file to be played
+- `%offset`: time in seconds where to start playing (used for seeking)
+
+Here's an example using `mplayer`:
+```
+jukebox_command = mplayer -ss %offset %path
+```
+
+Or using `mpv`:
+```
+jukebox_command = mpv --start=%offset %path
+```
+
+Setting the output volume isn't currently supported.
+
+## Allowing users to act on the jukebox
+
+The jukebox mode is only accessible to chosen users. Granting (or revoking)
+jukebox usage rights to a specific user is done with the [CLI](cli.md):
+
+```
+$ supysonic-cli user setroles --jukebox <username>
+```
