Application developers can use the Fabric tutorials to get started building their own solutions. Start working with Fabric by deploying the test network on your local machine. You can then use the steps provided by the Deploying a smart contract to a channel tutorial to deploy and test your smart contracts. The Writing Your First Application tutorial provides an introduction to how to use the APIs provided by the Fabric SDKs to invoke smart contracts from your client applications. For an in depth overview of how Fabric applications and smart contracts work together, you can visit the Developing Applications topic.
The Deploying a smart contract to a channel tutorial can also be used by network operators to learn how to use the Fabric chaincode lifecycle to manage smart contracts deployed on a running network. Both network operators and application developers can use the tutorials on Private data and CouchDB to explore important Fabric features. When you are ready to deploy Hyperledger Fabric in production, see the guide for Deploying a production network.
There are two tutorials for updating a channel: Updating a channel configuration and Updating the capability level of a channel, while Upgrading your components shows how to upgrade components like peers, ordering nodes, SDKs, and more.
Finally, we provide an introduction to how to write a basic smart contract, Chaincode for Developers.
