+ratings-based-shuffle
+=====================
+
+Simple mpv script to easily customize random playlist song selection.
+
+Usage
+-----
+
+Every file initially has a 'rating' of `1`. Using the upvote/downvote keybindings, the rating of the currently playing file can be multiplied by 1.1 or 0.9. In RBS mode (activated by another keybinding), a new file is randomly chosen (chance [rating]/[files in playlist]) after playback of any file is completed.
+
+Installation and configuration
+------------------------------
+
+Place `ratings-based-shuffle.lua` in your `~/.config/mpv/scripts`.
+
+Copy `ratings-based-shuffle.conf` into `~/.config/mpv/script-opts` and adjust the option values: set `directory` to the location of the files you want to play. Ratings will be saved in the file specified by `ratings_file`. Example:
+
+```
+directory=/home/username/Music/BigPlaylist
+ratings_file=/home/username/.config/mpv/rbs-ratings.txt
+```
+
+Set up the keybindings in your `input.conf` (usually located in `~/.config/mpv`):
+
+```
+Alt+r script-message RBS-init
+Alt+UP script-message RBS-upvote
+Alt+DOWN script-message RBS-downvote
+```
+
+Technical details
+-----------------
+
+Only absolute paths are stored in the `ratings_file`:
+
+```json
+{
+	"/home/username/Music/BigPlaylist/Topic/Directory/Song Name.mp3":1.100000,
+	"/home/username/Music/BigPlaylist/Another topic/LoremIpsum.mp3":0.810000
+}
+```
