 ### Prerequisites
 
 The following prerequisites are needed to run this sample:
+* You need to run this sample from your GOPATH. If you have downloaded the
+  `fabric-samples` directory outside your GOPATH, then you need to copy or

 * Fabric docker images. By default the `network/network.sh` script will look for
   fabric images with the `latest` tag, this can be adapted with the `-i` command
   line parameter of the script.
 * A local installation of `configtxgen` and `cryptogen` in the `PATH` environment,
   or included in `fabric-samples/bin` directory.

 ```
-peer chaincode instantiate -o irs-orderer:7050 -C irs -n irscc -l golang -v 0 -c '{"Args":["init","auditor","100000","rrprovider","myrr"]}' -P "AND(OR('partya.peer','partyb.peer','partyc.peer'), 'auditor.peer')"

 ```
+
 This sets an auditing threshold of 1M, above which the `auditor` organization
 needs to be involved. It also specifies the `myrr` reference rate provided by
 the `rrprovider` organization.
 
 To set a reference rate:
 ```
-peer chaincode invoke -o irs-orderer:7050 -C irs --waitForEvent -n irscc --peerAddresses irs-rrprovider:7051 -c '{"Args":["setReferenceRate","myrr","3"]}'
+peer chaincode invoke -o irs-orderer:7050 -C irs --waitForEvent -n irscc --peerAddresses irs-rrprovider:7051 -c '{"Args":["setReferenceRate","myrr","300"]}'
 ```
 Note that the transaction is endorsed by a peer of the organization we have
 specified as providing this reference rate in the init parameters.
 
 To create a swap named "myswap":
