+Refer the section [Build the cip core image](README.m-com-x86.md#build-the-cip-core-image) to create the image with Software update enabled,
+
+Copy the .swu file generated from the first build to temporary folder, which will be used for swupdate.
+
+Create second image(RT Kernel image) so, additionally select RT Kernel option on top of SWUpdate image here.
+
+Flash the image with RT Kernel to USB and boot the image from USB. Copy the .swu file from the temporary folder to M-COM device.
+
+For verification, please follow the [SWUpdate verification steps](../README.swupdate.md#swupdate-verification)
+
+## Secure Boot Configuration and Verification
+
+**Note:**
+* All the steps are specific to M-COM RT X86 V1 device hence consult device specific manual for other devices for Secure Boot verification.
+
+Copy KeyTool.efi and UEFI keys into USB stick as mentioned in [Secure boot key enrollment](../README.secureboot.md#secure-boot-key-enrollment)
+
+Insert USB memory stick to M-COM device.
+
+Power on and Press F12 key to Enter BIOS setup.
+
+**Note:**
+* if you want to restore the default BIOS settings then
+Under "Save & Exit" tab, Click on "Restore User Defaults" and select "Yes" to restore default values.

+
+Now the keys are injected, remove the USB stick.
+
+Refer the section [Build the cip core image](README.m-com-x86.md#build-the-cip-core-image) to create secure boot enabled image,
+
+Once build is completed, flash the Secure Boot image to USB stick and insert the USB memory stick to M-COM device.
+
+Power on and Press F12 key to Enter BIOS setup.
+
+In the BIOS, Configure the device to boot from USB by following below steps
