+
+            ## 🎛️ How it works
+
+            - **8 style slots** — Rock, Metal, Jazz, Funk, Electronic, Hip Hop, Latin, Punk
+            - **Intensity** — shapes groove density in real time, from skeleton to full arrangement
+            - **Chaos** — injects ghost notes, fills and random hits that grow wilder as it climbs
+            - **Full MIDI learn** — map everything to your foot controller or fader
+            - **Works headless** — no GUI needed during performance
