+### Collecting Jellyfin logs
+
+The new `jellyfin()` source, reads Jellyfin logs from its log file output.
+
+Example minimal config:
+```
+source s_jellyfin {
+  jellyfin(
+    base-dir("/path/to/my/jellyfin/root/log/dir")
+    filename-pattern("log_*.log")
+  );
+};
+```
+
+For more details about Jellyfin logging, see:
+ * https://jellyfin.org/docs/general/administration/configuration/#main-configuration
+ * https://jellyfin.org/docs/general/administration/configuration/#log-directory
+
+As the `jellyfin()` source is based on a `wildcard-file()` source, all of the
+`wildcard-file()` source options are applicable, too.
