+====== Getting started with the LED Ring expansion deck ======
+To get started with the LED Ring expansion deck you can either control the LEDs using the client, or by code.
+==== Using the Client ====
+Start the cfclient
+Connect to your Crazyflie and make sure your //LED// tab is visible.
+If not, go to View -> Tabs -> LED tab
+Now you can address each LED individually and set its RGB color.
+==== Using code ====
+You can easily control the LEDs by using the [[https://github.com/bitcraze/crazyflie-lib-python|Crazyflie Python lib]]
+There's two scripts in //Examples// that covers the basics:
+  * basicLedparamSync.py
+  * basicLedmemSync.py
+You can then modify the scripts to your needs by adjusting the color effects, fade effects, RBG values, timings and much more. There's really no limit to what you can do with this!
