# - Before building the Docker, ensure that you setup the initial configs of the node.

# - You have to setup email credentials as well as the account from the master node, or just the credentials.

# - Ensure that the nodes were able to initialize as well as shutdown gracefully in the sense that the files were able to encrypt-decrpyt such files.
