-You need to install Node.js version 8.9.x to use the sample application code.

-Execute the following commands to install the required dependencies:
 
 ```
-cd fabric-samples/off_chain_data

+This command will deploy an instance of the Fabric test network. The network
+consists of an ordering service, two peer organizations with one peers each, and
+a CA for each org. The command also creates a channel named `mychannel`. The
