@ -65,9 +65,6 @@ Building and Running
The sample updates the LED strip periodically. The update frequency can be
modified by changing the :kconfig:option:`CONFIG_SAMPLE_LED_UPDATE_DELAY`.
If there is no chain-length property in the devicetree node, you need to set
the number of LEDs in the :kconfig:option:`CONFIG_SAMPLE_LED_STRIP_LENGTH` option.
Then build and flash the application:
