+Background:
+    - These binaries are signed with a leaf certificate of the Microsoft Corporation KEK CA 2023.
+    - These binaries should be used for systems that trust the Microsoft Corporation KEK CA 2023 certificate.
+    - These binaries hashes are broken up by architecture
+        - X64
+        - Ia32
+        - Arm
+        - Aarch64
+    - Purely hash based revocations. These do not contain the 2011 Windows CA nor do they contain SVNs.
+    - These binaries carry the same DBX revocations as the `edk2-2011-signed-secureboot-binaries`, but
+    are signed with the 2023 KEK for systems that have transitioned to it. Consult the
+    `PreSignedObjects\DBX\dbx_info_msft_<date>.json` file for more information.
