 =================
 
 This guide provides an overview of how to set up the Airflow agent in your Flyte deployment.
+Please note that the you don't need an Airflow cluster to run the airflow tasks. Flytekit will
+automatically compile it to a Flyte task and execute it on the Flyte cluster.
 
 Specify agent configuration
 ----------------------------
 
-TK
+.. tabs::
+
+    .. group-tab:: Flyte binary
+
+      Edit the relevant YAML file to specify the agent.

+
+        kubectl edit configmap flyte-sandbox-config -n flyte

+
+      Create a file named ``values-override.yaml`` and add the following configuration to it.
+

+Upgrade the Flyte Helm release
+------------------------------
+
+.. tabs::
+
+  .. group-tab:: Flyte binary
+
+    .. code-block:: bash
+
+      helm upgrade <RELEASE_NAME> flyteorg/flyte-binary -n <YOUR_NAMESPACE> --values <YOUR_YAML_FILE>
+
+    Replace ``<RELEASE_NAME>`` with the name of your release (e.g., ``flyte-backend``),
+    ``<YOUR_NAMESPACE>`` with the name of your namespace (e.g., ``flyte``),
+    and ``<YOUR_YAML_FILE>`` with the name of your YAML file.
+
+  .. group-tab:: Flyte core
+
+    .. code-block:: bash
+
+      helm upgrade <RELEASE_NAME> flyte/flyte-core -n <YOUR_NAMESPACE> --values values-override.yaml
+
+    Replace ``<RELEASE_NAME>`` with the name of your release (e.g., ``flyte``)
+
