-### Rendering Excalidraw only on client
+### Next.js
 
 Since _Excalidraw_ doesn't support server side rendering, you should render the component once the host is `mounted`.
 
-The following worfklow shows one way how to render Excalidraw on Next.js. We'll add more detailed and alternative Next.js examples, soon.
+Here are two ways on how you can render **Excalidraw** on **Next.js**.
+
+
+
+1. Using **Next.js Dynamic** import [Recommended].
+
+Since Excalidraw doesn't support server side rendering so you can also use `dynamic import` to render by setting `ssr` to `false`.
+
+```jsx showLineNumbers
+import dynamic from "next/dynamic";
+const Excalidraw = dynamic(
+  async () => (await import("@excalidraw/excalidraw")).Excalidraw,
+  {
+    ssr: false,
+  },
+);
+export default function App() {
+  return <Excalidraw />;
+}
+```
+
+Here is a working [demo](https://codesandbox.io/p/sandbox/excalidraw-with-next-dynamic-k8yjq2).
+
+
+2. Importing Excalidraw once **client** is rendered.
 
 ```jsx showLineNumbers
 import { useState, useEffect } from "react";
 export default function App() {
   const [Excalidraw, setExcalidraw] = useState(null);
   useEffect(() => {
-    import("@excalidraw/excalidraw").then((comp) => setExcalidraw(comp.Excalidraw));
+    import("@excalidraw/excalidraw").then((comp) =>
+      setExcalidraw(comp.Excalidraw),
+    );
   }, []);
   return <>{Excalidraw && <Excalidraw />}</>;
 }
 ```
 
+Here is a working [demo](https://codesandbox.io/p/sandbox/excalidraw-with-next-5xb3d)
+
 The `types` are available at `@excalidraw/excalidraw/types`, you can view [example for typescript](https://codesandbox.io/s/excalidraw-types-9h2dm)
 
+### Preact
+
+Since we support `umd` build ships with `react/jsx-runtime` and `react-dom/client` inlined with the package. This conflicts with `Preact` and hence the build doesn't work directly with `Preact`.
+
+However we have shipped a separate build for `Preact` so if you are using `Preact` you need to set `process.env.IS_PREACT` to `true` to use the `Preact` build.
+
+Once the above `env` variable is set, you will be able to use the package in `Preact` as well.
