+Various session related parameters can be set via special options, either
+in a configuration file provided via '-readconfig' or directly on the
+command line.
+
+@example
+Setting a specific initiator name to use when logging in to the target
+-iscsi initiator-name=iqn.qemu.test:my-initiator
+@end example
+
+@example
+Controlling which type of header digest to negotiate with the target
+-iscsi header-digest=CRC32C|CRC32C-NONE|NONE-CRC32C|NONE
+@end example
+
+These can also be set via a configuration file
+@example
+[iscsi]
+ user = "CHAP username"
+ password = "CHAP password"
+ initiator-name = "iqn.qemu.test:my-initiator"
+ # header digest is one of CRC32C|CRC32C-NONE|NONE-CRC32C|NONE
+ header-digest = "CRC32C"
+@end example
+
+
+Setting the target name allows different options for different targets
+@example
+[iscsi "iqn.target.name"]
+ user = "CHAP username"
+ password = "CHAP password"
+ initiator-name = "iqn.qemu.test:my-initiator"
+ # header digest is one of CRC32C|CRC32C-NONE|NONE-CRC32C|NONE
+ header-digest = "CRC32C"
