 =========
 
-We offer tutorials to get you started with Hyperledger Fabric.
-The first is oriented to the Hyperledger Fabric **application developer**,
-:doc:`write_first_app`. It takes you through the process of writing your first
-blockchain application for Hyperledger Fabric using the Hyperledger Fabric
-`Node SDK <https://github.com/hyperledger/fabric-sdk-node>`_. For a more developer
-focused experience for developing apps, check out :doc:`developapps/developing_applications`.
-
-We also have a tutorial oriented towards the Hyperledger Fabric network
-operators, :doc:`build_network`. This one walks you through the process of
-establishing a blockchain network using Hyperledger Fabric and provides
-a basic sample application to test it out.
+Application developers can use the Fabric tutorials to get started building their
+own solutions. Start working with Fabric by deploying the `test network <./test_network.html>`_
+on your local machine. You can then use the steps provided by the :doc:`deploy_chaincode`
+tutorial to deploy and test your smart contracts. The :doc:`write_first_app`
+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 :doc:`developapps/developing_applications` topic.
+
+The :doc:`deploy_chaincode` 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 <./private_data_tutorial.html>`_ and `CouchDB <./couchdb_tutorial.html>`_
+to explore important Fabric features. When you are ready to deploy Hyperledger
+Fabric in production, see the guide for :doc:`deployment_guide_overview`.
