+### Shuffle panel
+
+One of unison's main feature is a complete shuffle system based on criterias, aka a smart playlist.
+
+You have two options:
+* **Add to queue** allows you to add a defined number of songs to the queue.
+* **Continuous shuffle** allows you, as long as the program is running, to automatically add songs to the queue.
+
+Each of these options work with filters, but if none are selected, it is based on the entire library.
