-# PCD Library instance implemented with PCD Protocol
+## @file
+# Instance of PCD Library using PCD Protocol.
 #
-# This library instance implement the APIs listed 
-#  in PCD library class defined in MDE library specification.
-#  It is used by modules in DXE phase.
-# Copyright (c) 2007, Intel Corporation.
+# There are two PCD PPIs as follows:
+#   1) PCD_PROTOCOL
+#      It is EDKII implementation which support Dynamic/DynamicEx Pcds.
+#   2) EFI_PCD_PROTOCOL
+#      It is defined by PI specification 1.2, Vol 3 which only support dynamicEx 
+#      type Pcd.
 #
-#  All rights reserved. This program and the accompanying materials
+# For dynamicEx type PCD, it is compatible between PCD_PROTOCOL and EFI_PCD_PROTOCOL.
+#
+# This library instance uses the PCD_PROTOCOL to handle dynamic PCD request and use
+# EFI_PCD_PROTOCOL to handle dynamicEx type PCD.
