 #  Access PXE-compatible devices for network access and network booting.
 #
 #  This driver provides PXE Base Code Protocol which is used to accessing
-#  PXE-compatible device for network access or booting. It could work together
-#  with an IPv4 stack, an IPv6 stack or both.
+#  PXE-compatible device for network access or booting. This driver supports
+#  both IPv4 and IPv6 network stack.
 #
+#  Notes:
+#  1) This driver can't co-work with the UefiPxeBcDxe driver in MdeModulePkg.
+#  2) This driver includes more bug fixes and supports more features (e.g. IPv6,
+#     MTFTP windowsize) than the UefiPxeBcDxe driver in MdeModulePkg. So, we
+#     recommend using this driver even though both of them can be used.
