+# Next.js
+
+Since we provide [react](/docs/recipes/react) support out of box, we can use it directly in [Next.js](https://nextjs.org/).
+
+## Install the Dependencies
+
+Except the `@milkdown/kit` and theme. We need to install the `@milkdown/react`, which provide lots of abilities for react in milkdown.
+
+```bash
+# install with npm
+npm install @milkdown/react
+npm install @milkdown/kit
+npm install @milkdown/theme-nord
+```
+
+## Create a Component
+
+Create a component is pretty easy.
+
+```tsx
+import { Editor, rootCtx } from "@milkdown/kit/core";
+import { commonmark } from "@milkdown/kit/preset/commonmark";
+import { Milkdown, MilkdownProvider, useEditor } from "@milkdown/react";
+import { nord } from "@milkdown/theme-nord";
+import React from "react";
+
+const MilkdownEditor: React.FC = () => {
+  const { editor } = useEditor((root) =>
+    Editor.make()
+      .config(nord)
+      .config((ctx) => {
+        ctx.set(rootCtx, root);
+      })
+      .use(commonmark),
+  );
+
+  return <Milkdown />;
+};
+
+export const MilkdownEditorWrapper: React.FC = () => {
+  return (
+    <MilkdownProvider>
+      <MilkdownEditor />
+    </MilkdownProvider>
+  );
+};
+```
