 New implementation of https://github.com/Programvareverkstedet/grzegorz
 
-## Test it out
+## Feature wishlist
 
-```sh
+- [ ] Feature parity with old grzegorz
-# NixOS
+  - [X] Rest API
-nix run "git+https://git.pvv.ntnu.no/Projects/greg-ng#" -- --mpv-socket-path /tmp/mpv.sock
+  - [ ] Rest API docs
-
+  - [ ] Metadata fetcher
-# Other (after git clone and rust toolchain has been set up)
+  - [ ] Init mpv with image of grzegorz
-cargo run -- --mpv-socket-path /tmp/mpv.sock
+- [ ] Save playlists to machine
-```
+- [ ] Cache playlist contents to disk
-
+- [ ] Expose service through mpd protocol
-See also https://git.pvv.ntnu.no/Projects/grzegorz-clients for frontend alternatives
+- [ ] Users with playlists and songs (and auth?)
-
+- [ ] Some kind of fair scheduling for each user
-## Debugging
+- [ ] Max time to avoid playlist songs
-
+- [ ] Expose video/media stream so others can listen at home
-```sh
+- [ ] Syncope support >:)
-RUST_LOG=greg_ng=trace,mpvipc=trace cargo run -- --mpv-socket-path /tmp/mpv.sock
+- [ ] Jitsi support >:)))
-```
+- [ ] Show other media while playing music, like grafana or bustimes
+- [ ] Soft shuffle
+- [ ] Libre.fm integration
+- [ ] Karaoke mode lmao
