 Blissify - analyze an MPD library and make smart playlists
 ==========================================================
 
-Blissify is an [MPD](https://www.musicpd.org/) plugin
+Blissify is a program used to make playlists of songs that sound alike
+from your [MPD](https://www.musicpd.org/) track library, à la Spotify radio.
+
+Under the hood, it is an [MPD](https://www.musicpd.org/) plugin
 for [bliss](https://crates.io/crates/bliss-audio).
 
-You can use it to make playlists of songs that sound alike from an MPD
-library.
+Blissify needs first to analyze your music library, i.e. compute and store
+a series of features from your songs, extracting the tempo, timbre,
+loudness, etc.
 
-Note: the `blissify-rs` crate is outdated. Use this crate (`blissify`) instead.
+After that, it is ready to make playlists: play a song to start from, run
+`blissify --playlist 30`, and voilà! You have a playlist of 30 songs that
+sound like your first track.

 This will add 100 songs similar to the song that is currently
 playing on MPD, starting with the closest possible.

+Details

+If you are interested about what is happening under the hood, or want to make
+a similar plug-in for other audio players, see
+[bliss' doc](https://docs.rs/crate/bliss-audio/0.1.3).
