 The Application Insights agent or SDK preprocesses telemetry and metrics before sending the data to Azure. Then it's ingested and processed further before it's stored in Azure Monitor Logs (Log Analytics). For this reason, an Azure account is required to use Application Insights.

 ## How do I instrument an application?
 
-[Auto-instrumentation](codeless-overview.md) is the preferred instrumentation method. It requires no developer investment and eliminates future overhead related to [updating the SDK](sdk-support-guidance.md). It's also the only way to instrument an application in which you don't have access to the source code.

It's also the only way to instrument an application in which you don't have access to the source code.
 
 You only need to install the Application Insights SDK if:
 
 - You require [custom events and metrics](api-custom-events-metrics.md).
 - You require control over the flow of telemetry.

+- [Autoinstrumentation](codeless-overview.md) isn't available, typically because of language or platform limitations.
 
 To use the SDK, you install a small instrumentation package in your app and then instrument the web app, any background components, and JavaScript within the webpages. The app and its components don't have to be hosted in Azure.
 
 The instrumentation monitors your app and directs the telemetry data to an Application Insights resource by using a unique token. The effect on your app's performance is small. Tracking calls are nonblocking and batched to be sent in a separate thread.
