 ### 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
- move the interest rate sample into your GOPATH.
 * 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.
-* Vendoring the chaincode. In the `chaincode` directory, run `govendor init` and
- `govendor add +external` to vendor the shim from your local copy of fabric.
