As I'm not good with documentation, this is one version that may be
suitable.
This one is based on README.fcoe. The other patch is based on README.iscsi.
I'm happy to accept any comments on either version as to which one is
more suitable
and what sort of modifications / edits are required to get it to a
suitable format.

+Configure target's logical units as 'passthrough' to real devices.
+
+1. Preparation
+Compile tgtd & tgtadm as per instructions for SCSI transport of choice.
+
+e.g. for iSCSI
+fujita@host:~/git/tgt/usr$ make ISCSI=1
+
+
+2. Starting the daemon
+
+host:~/tgt# ./usr/tgtd
+
+
+
+3. Configuration
+
+You need to setup a target and luns as you do with other target
+drivers. There is no special hack for the passthrough module.
+
+To setup a logical unit for passthrough operation, three options are required:
+ - Specify device type as passthruough
+ "--device-type=pt"
+ - Backing store type is the '/dev/sg' paths
+ "--bstype=sg"
+ - Backing store path to use
+ "-b /dev/sg4"
+
+
+Here's a simple example:
+
+Setup an iSCSI target:
+host:~/tgt# ./usr/tgtadm --lld iscsi --op new --mode target \
+ --tid 1 -T iqn.2001-04.com.example:storage.vtl.amiens.sys1.xyz
+
+Define LUN 1 connected through to /dev/sg4
+host:~/tgt# ./usr/tgtadm --lld iscsi --op new --mode logicalunit \
+ --tid 1 --lun 1 --device-type=pt --bstype=sg -b /dev/sg4
+
+Now allow all initiators to connect
+host:~/tgt# ./usr/tgtadm --lld iscsi --op bind --mode target \
+ --tid 1 -I ALL
+
+
+4. Shutting down the daemon
+host:~/tgt# tgtadm --op unbind --mode target --tid 1 -I ALL
+host:~/tgt# tgtadm --op delete --mode conn --tid 1
+host:~/tgt# tgtadm --op delete --mode target --tid 1
+host:~/tgt# tgtadm --op delete --mode system
+
+
+Enjoy!
