-#+TITLE: mpd-stats
-
-Log played songs to extract statistics. This is similar to what libre.fm used to do, but locally.
-
-* Logging
-Collect logs from mpd. A log record is composed of the following fields:
-- id: UUID
-- song's name: the name of the song
-- song's album: the name of the album
-- song's artist: the name of the artist
-- song's duration: the duration of the song
-- date: date the song was played
-
-The logs are recorded in a database (sqlite3 to start).
-* Install
-The Makefile assumes the system is running Linux and systemd.
-
-Run =make install=. This will:
-- install the binary in your =GOPATH= (using =go install=)
-- install a systemd unit file under =$HOME/.config/systemd/user=
-- reload systemd unit files
-- start the service
