Configuring & setting up MPD is beyond the scope of this manual; see the MPD manual here.
One note, however: in order for mpdpopm
to function, MPD
must be configured to enable the sticker database. This is done via
the sticker_file
configuration item. The user as whom
mppopmd
is run will need access to the file named therein and
its parent directories. See
here for details.
