convert esd to wim

I am trying to make a flash drive with the .WIM format to do a clean install of Windows 1903.

I already have one s .ESD.

I have watches so many videos and read many tutorials but it is not sinking in. I can't seem to get started.

Do you first download the MCT which is .ESD to the flash drive to be converted?

Please no links as I have seen them all and as I said they are not sinking in.

Thank you for a push.

Yes, more than one way to skin a cat. Thanks for placing the post in the proper thread.
