title: How does the golang chaincode in the marbles nodejs example works?
body: <p>I have got this example <a href="https://github.com/IBM-Blockchain/marbles" rel="nofollow">https://github.com/IBM-Blockchain/marbles</a> run locally. I saw that the example downloaded the golang chaincode from <a href="https://github.com/ibm-blockchain/marbles-chaincode" rel="nofollow">https://github.com/ibm-blockchain/marbles-chaincode</a>. And the chaincode was stored on harddisk at /marbles/node_modules/ibm-blockchain-js/temp/unzip.
  Could you please explain how the golang chaincode was executed inside the nodejs code?  </p>
