 Sentry integration with Azure Functions is done by calling `.UseSentry()` and specifying the options, for example:
 
+```csharp {"onboardingOptions": {"performance": "11-13"}}
+using Sentry.Azure.Functions.Worker;
+
+var builder = FunctionsApplication.CreateBuilder(args);
+
+builder.UseSentry(options =>
+{
+    options.Dsn = "___PUBLIC_DSN___";
+    // When configuring for the first time, to see what the SDK is doing:
+    options.Debug = true;
+    // Set traces_sample_rate to 1.0 to capture 100% of transactions for performance monitoring.
+    // We recommend adjusting this value in production.
+    options.TracesSampleRate = 1.0;
+});
+
+builder.Build().Run();
+```
 
 <Alert>
 
 If using the ASP.NET Core integration add `UseSentry` to the `ConfigureFunctionsWebApplication` call instead.
