 # Metabase Embedding SDK for React
 
 The Metabase Embedding SDK for React offers a way to integrate Metabase into your application more seamlessly and with
 greater flexibility than using the current interactive embedding offering based on iframes.

-# Known limitations
-
-- The Metabase Embedding SDK does not support server-side rendering (SSR) at the moment.
-    - If you are using a framework with SSR support such as Next.js or Remix, you have to ensure that the SDK components
-      are rendered on the client side.
-    - For example, you can apply the `"use client"` directive on Next.js or use the `remix-utils/ClientOnly` component
-      on Remix.
-- Embedding multiple instances of interactive dashboards on the same page are not supported.
-    - Please use static dashboards if you need to embed multiple dashboards on the same page.
