Since the EDK2 GenerateCapsule script is out of date and it doesn't generate the supported version capsule file, the document should refer the mkeficapsule in tools.

Thanks for the change.
Could you, please, adjust the same in chapter "Enabling Capsule Authentication" below.
Currently, we do not have support for adding authentication header to the capsule. This is because I have been using the GenerateCapsule script in edk2 for generation of a capsule with authentication header. I think adding the signature to the capsule is easier when done through a python script rather than C code. I am working on adding support for the latest version of the EFI_FIRMWARE_MANAGEMENT_CAPSULE_IMAGE_HEADER in the GenerateCapsule script in edk2. Meanwhile, would it be possible to have support for the version 2 of this header in the capsule driver -- it is a minor change and I already have a patch for it. If you are fine, I can submit a patch for the same.

As per the UEFI specification, the capsule file needs to be placed on the EFI System Partition, under the \EFI\UpdateCapsule directory. The
