+
+At this point, you should have integrated Sentry into your JavaScript application and should already be sending data to your Sentry project.
+
+Now's a good time to customize your setup and look into more advanced topics. Our next recommended steps for you are:
+
+- Extend Sentry to your backend using one of our [SDKs](/)
+- Learn how to [manually capture errors](/platforms/javascript/usage/)
+- Continue to [customize your configuration](/platforms/javascript/configuration/)
+- Get familiar with [Sentry's product features](/product) like tracing, insights, and alerts
