 a rust application to scrobble your currently playing song on last.fm with mpris
 
-upd 2024-08-27: i'm adding a home-manager module, eventually!
-
 ## limitations
 
 unfortunately, because of how most mpris players work, the [Track_Id](https://specifications.freedesktop.org/mpris-spec/latest/Player_Interface.html#Simple-Type:Track_Id) (unique identifier for every song in the tracklist) object is very rarely supported, or, if supported, implemented incorrectly (looking at you, [Cider](https://cider.sh/)) meaning it is impossible to tell if the track has been played twice in a row. this means you cannot have succssive scrobbles of the same song, sorry! besides this, i'd say the program is feature complete.

 1. the nix way
 
+    simply just run it:
+
     ```sh
     nix run git+https://git.reidlab.pink/reidlab/lastfmpris.git
     ```
 
+    or import it into your flake like so:
+
+    ```nix
+    lastfmpris.url = "git+https://git.reidlab.pink/reidlab/lastfmpris.git";
+    # in your `homeManagerConfiguration`:
+    imports = [
+      inputs.lastfmpris.homeManagerModules.lastfmpris;
+    ];
+    ```
+
+    and then use it as a service in your `homeManagerConfiguration`:
+
+    ```nix
+    services.lastfmpris = {
+      enable = true;
+      settings = {
+        # player_bus = "org.mpris.MediaPlayer2.mpv";
+        username = "ILoveLastDotFm";
