For this project, we'll be working with the Hyperledger Fabric binaries and Docker images provided in the Hyperledger Fabric GitHub repository that we downloaded earlier.

Next, let's set up the environment for our project. Download the Bankchain directory from the GitHub repository, at this link: https://github.com/PacktPublishing/Blockchain-Development-for-Finance-Projects/tree/master/Chapter%204/bankchain.

Save the directory to the fabric-samples repository that you would have downloaded while installing Hyperledger Fabric. In the next sections, we'll walk through the different artifacts in the repository that we have to create or modify, to build our network.
