+After commissioning is successful, announce OTA provider's presence using

 ```

 ## Apply update request

-Provider for applying the OTA image.
+Provider for applying the OTA image. Use the following command from OTA
+requestor prompt
 
 ```
-esp32> ApplyUpdateRequest <OTAProviderIpAddress> <OTAProviderNodeId>

-After this step device should reboot and start running hello world example.
+Then reboot the device manually to boot from upgraded OTA image.
 
 ## ESP32 OTA Requestor with Linux OTA Provider
 
 -   Build the [Linux OTA Provider](../../ota-provider-app/linux)
--   Run the Linux OTA Provider with
-    [hello world OTA image](http://shubhamdp.github.io/esp_ota/esp32/hello-world-for-linux-provider.bin).
-    This OTA image is built for ESP32, it will not work on other devices.
+-   Run the Linux OTA Provider with OTA image.
 
 ```
-./out/debug/chip-ota-provider-app -f hello-world-for-linux-provider.bin
+./out/debug/chip-ota-provider-app -f hello-world.bin
 ```
 
 -   Provision the Linux OTA Provider using chip-tool
 
 ```
-./out/debug/chip-tool pairing 12345 20202021
+./out/debug/chip-tool pairing onnetwork 12345 20202021
