+# jellyfin-radio
+
+Ever dreamt of having your own radio station, but without the hassle of choosing the music yourself?
+
+jellyfin-radio randomly plays Songs from a Jellyfin collection and streams it via .mp3, which can be streamed for example on a Yamaha MusicCast System.
+
+The usage is rather simple. It is recommended to run this as a Docker container. An example docker-compose configuration might look like this:
+
+```yaml
+version: "3"
+services:
+    radio:
+        image: ghcr.io/jhbruhn/jellyfin-radio:main
+        ports:
+            - "3000:3000"
+        restart: unless-stopped
+        environment:
+            JELLYFIN_URL: http://<jellyfin-server>:<jellyfin-port>
+            JELLYFIN_API_KEY: <api-key> # generated in jellyfin UI
+            JELLYFIN_COLLECTION_NAME: Music # name of the Collection you want to play music from
+            SONG_PREFETCH: 2 # optional: Define how many songs jellyfin-radio should fetch in advance
+```
