 #  Client-side iSCSI service.

 #  The iSCSI driver provides iSCSI service in the preboot environment and supports
-#  booting over iSCSI.
+#  booting over iSCSI. This driver supports both IPv4 and IPv6 network stack.
+#
+#  Notes: 
+#  1) This driver can't co-work with the IScsiDxe driver in MdeModulePkg. 
+#  2) This driver includes more bugs fix and supports more features (e.g. IPv6, Dns 
+#     support for target URL configuration, iSCSI keyword support) than the IscsiDxe 
+#     driver in MdeModulePkg. So, we recommand to use this driver even both of them 
+#     can be used.
+#  3) This driver depends on the OpenSSL building. To use this driver, please follow 
+#     the instructions found in the file "Patch-HOWTO.txt" located in 
+#     CryptoPkg\Library\OpensslLib to enable the OpenSSL building first.
