 ### Hardware Required
 
-* Prepare an ESP32-C6 development board as an OpenThread Sleepy End Device (SED).   
-* Connect the board using a USB cable for power supply and programming.  
-* Choose another ESP32-C6 as the OpenThread Leader.

 ## Configure the Openthread Dataset
 
-* Run [ot_cli](../ot_cli/) on another ESP32-C6 device to create openthread dataset configuration and start an openthread network as the leader.  
-* Configure the Openthread dataset using `idf.py menuconfig` in `Component config ---> Openthread ---> Thread Operation Dataset`, ensuring that the openthread sleepy device's dataset matches the dataset of the leader.  
-
-## Erase the ot_storage
-
-If desired, erase the ot_storage by running `idf.py -p <PORT> erase-flash` before flashing the board to remove previous examples or other project data.
