 ### Overview
 
-The Formbricks JS SDK is a 2-in-1 SDK for seamlessly integrating both App Surveys and Website Surveys into your projects. In this section, we'll explore how to leverage the SDK specifically for **app** surveys. It’s available on npm [here](https://www.npmjs.com/package/@formbricks/js/).
+The Formbricks JS SDK is a versatile solution for integrating surveys into both web apps and websites. It adapts based on the presence of a `userId`. If a `userId` is provided, the SDK handles authenticated surveys for logged-in users in web apps. If no `userId` is provided, the SDK can still seamlessly run surveys on public-facing websites. The SDK is available on npm [here](https://www.npmjs.com/package/@formbricks/js/).
