Then, use the composer network install, start, or upgrade command to deploy your business network onto Hyperledger Fabric. To update the definitions, you must run the composer network upgrade command. The following sections describe the process for deploying and upgrading business network definitions.
Once you have downloaded the program, you should start your network. You can find examples of different setups in public play areas. Click on the “Export” button to download your files.
