-If you are also using Performance Monitoring for [JavaScript](/platforms/javascript/performance/) you can use a helper function to continue the trace started from your backend in order to [connect services](/platforms/javascript/performance/connect-services/#navigation-and-other-xhr-requests).
+If you're also using Performance Monitoring for [JavaScript](/platforms/javascript/performance/), you can use a helper function to continue the trace and propagate the Dynamic Sampling context started from your backend in order to [connect services](/platforms/javascript/performance/connect-services/#navigation-and-other-xhr-requests). (The Dynamic Sampling context contains additional trace-related data that is used for trace-based sampling.)
 Add the following line to your blade template rendering the `<head/>` of your page:
 
 ```php {filename:app.blade.php}
 <head>
 ...
-{!! \Sentry\Laravel\Integration::sentryTracingMeta() !!}
+{!! \Sentry\Laravel\Integration::sentryMeta() !!}
 ...
 </head>
 ```
 
-This helper function will render a meta tag similar to this `<meta name="sentry-trace" content="49879feb76c84743ba5034bd2d3f1ca3-7cb5535c930d4666-1"/>`, which our JavaScript SDK will pick up and continue the trace. Therefore, your frontend and your backend are connected by way of the same trace.
+This helper function will render two meta tags similar to `<meta name="sentry-trace" content="49879feb76c84743ba5034bd2d3f1ca3-7cb5535c930d4666-1"/>` and `<meta name="baggage" content="sentry-trace_id=49879feb76c84743ba5034bd2d3f1ca3,sentry-sample_rate=0.2,sentry-transaction=my-transaction,sentry-public_key=public,sentry-release=1.0.0,sentry-environment=prod>`. Our JavaScript SDK will pick these up and then continue the trace and propagate the Dynamic Sampling context. 
+As a result, your frontend and your backend are connected by way of the same trace.
 
 Otherwise, other backend services with Performance Monitoring will connect automatically.
