 ## Azure Functions
 
-Due to how Azure Functions (and other FaaS services) handle incoming requests, they are not seen as `http` requests to the Node.js runtime. For this reason, Request -> Dependency correlelation will **not** work out of the box.
-To enable tracking here, you simply need to grab the context from your Function request handler, and wrap your Function with that context.
+Auto correlation in Azure Functions is supported automatically starting in 2.4.0, if using previous version following code should be added to handle the correlation available in Azure Functions environment.
 
-### Setting up Auto-Correlation for Azure Functions
-
-You do not need to make any changes to your existing Function logic.
-Instead, you can update the `default` export of your `httpTrigger` to be wrapped with some Application Insights logic:
