 `chaincode`: chaincode to invoke. There is an example chaincode in `chaincodes/sample.go`, which simply puts `key:value`. This is closely related to `args` parameter.
 
+`version`: the version of chaincode. This is left to empty by default.
+
 `args`: arguments to send with invocation, depending on your chaincode implementation. The chaincode used by this sample can be found in `chaincodes/sample.go`
 
 `num_of_conn`: number of gRPC connection established between client/peer, client/orderer. If you think client has not put enough pressure on Fabric, increase this.
