 ### Server Side Render (SSR)
 
+There are two options for server-side rendering styles, each with advantages and disadvantages:
+
+- **Inline mode**: there is no need to request additional style files during rendering. The advantage is to reduce additional network requests. The disadvantage is that the HTML volume will increase and the speed of the first screen rendering will be affected. Relevant discussion: [#39891](https://github.com/ant-design/ant-design/issues/39891)
+- **Whole export**: The antd component is pre-baked and styled as a css file to be introduced in the page. The advantage is that when opening any page, the same set of css files will be reused just like the traditional css scheme to hit the cache. The disadvantage is that if there are multiple themes in the page, additional baking is required
+
+#### Inline mode
+
 Use `@ant-design/cssinjs` to extract style:
 
 ```tsx
@@ -278,6 +285,119 @@ export default () => {

 ```
 
+#### Whole export
+
+If you want to detach a style file into a css file, try using the following script:
+
+```javascript
+// scripts/genAntdCss.mjs
+import fs from 'fs';
+import { extractStyle } from '@ant-design/static-style-extract';
+
+const outputPath = './public/antd.min.css';
+
+const css = extractStyle();
+fs.writeFileSync(outputPath, css);
+```
+
+You can choose to execute this script before starting the development command or before compiling. Running this script will generate a full antd.min.css file directly in the specified directory of the current project (e.g. public).
+
+Take Next.js for example（[example](https://github.com/ant-design/create-next-app-antd)）：
+
+```json
+// package.json
+{
+  "scripts": {
+    "dev": "next dev",
+    "build": "next build",
+    "start": "next start",
+    "lint": "next lint",
+    "predev": "node ./scripts/genAntdCss.mjs",
+    "prebuild": "node ./scripts/genAntdCss.mjs"
+  }
+}
+```
+
+Then, you just need to import this file into the `pages/_app.tsx` file:
+
+```tsx
+import { StyleProvider } from '@ant-design/cssinjs';
+import type { AppProps } from 'next/app';
+import '../public/antd.min.css';
+import '../styles/globals.css'; // add this line
+
+export default function App({ Component, pageProps }: AppProps) {
+  return (
+    <StyleProvider hashPriority="high">
+      <Component {...pageProps} />
+    </StyleProvider>
+  );
+}
+```
+
+#### Custom theme
+
+If you're using a custom theme for your project, try baking in the following ways:
+
+```tsx
+import { extractStyle } from '@ant-design/static-style-extract';
+import { ConfigProvider } from 'antd';
+
+const cssText = extractStyle((node) => (
+  <ConfigProvider
+    theme={{
+      token: {
+        colorPrimary: 'red',
+      },
+    }}
+  >
+    {node}
+  </ConfigProvider>
+));
+```
+
+#### Mixed theme
+
+If you're using a mixed theme for your project, try baking in the following ways:
+
+```tsx
+import { extractStyle } from '@ant-design/static-style-extract';
+import { ConfigProvider } from 'antd';
+
+const cssText = extractStyle((node) => (
+  <>
+    <ConfigProvider
+      theme={{
+        token: {
+          colorBgBase: 'green ',
+        },
+      }}
+    >
+      {node}
+    </ConfigProvider>
+    <ConfigProvider
+      theme={{
+        token: {
+          colorPrimary: 'blue',
+        },
+      }}
+    >
+      <ConfigProvider
+        theme={{
+          token: {
+            colorBgBase: 'red ',
+          },
+        }}
+      >
+        {node}
+      </ConfigProvider>
+    </ConfigProvider>
+  </>
+));
+```

 ### Shadow DOM Usage
 
 Since `<style />` tag insertion is different from normal DOM in Shadow DOM scenario, you need to use `StyleProvider` of `@ant-design/cssinjs` to configure the `container` property to set the insertion position:

 ### 服务端渲染
 
+服务端渲染样式有两种方案，它们各有优缺点：
+
+- **内联方式**：在渲染时无需额外请求样式文件，好处是减少额外的网络请求，缺点则是会使得 HTML 体积增大，影响首屏渲染速度，相关讨论参考：[#39891](https://github.com/ant-design/ant-design/issues/39891)
+- **整体导出**：提前烘焙 antd 组件样式为 css 文件，在页面中时引入。好处是打开任意页面时如传统 css 方案一样都会复用同一套 css 文件以命中缓存，缺点是如果页面中存在多主题，则需要额外进行烘焙
+
+#### 内联方式
+
 使用 `@ant-design/cssinjs` 将所需样式抽离：
 
 ```tsx

+#### 整体导出
+
+如果你想要将样式文件抽离到 css 文件中，可以尝试使用以下脚本：
+
+```javascript
+// scripts/genAntdCss.mjs
+import fs from 'fs';
+import { extractStyle } from '@ant-design/static-style-extract';
+
+const outputPath = './public/antd.min.css';
+
+const css = extractStyle();
+fs.writeFileSync(outputPath, css);
+```
+
+你可以选择在启动开发命令或编译前执行这个脚本，运行上述脚本将会在当前项目的指定（如： public 目录）目录下直接生成一个全量的 antd.min.css 文件。
+
+以 Next.js 为例（[参考示例](https://github.com/ant-design/create-next-app-antd)）：
+
+```json
+// package.json
+{
+  "scripts": {
+    "dev": "next dev",
+    "build": "next build",
+    "start": "next start",
+    "lint": "next lint",
+    "predev": "node ./scripts/genAntdCss.mjs",
+    "prebuild": "node ./scripts/genAntdCss.mjs"
+  }
+}
+```
+
+然后，你只需要在`pages/_app.tsx`文件中引入这个文件即可：
+
+```tsx
+import { StyleProvider } from '@ant-design/cssinjs';
+import type { AppProps } from 'next/app';
+import '../public/antd.min.css';
+import '../styles/globals.css'; // 添加这行
+
+export default function App({ Component, pageProps }: AppProps) {
+  return (
+    <StyleProvider hashPriority="high">
+      <Component {...pageProps} />
+    </StyleProvider>
+  );
+}
+```
+
+#### 自定义主题
+
+如果你的项目中使用了自定义主题，可以尝试通过以下方式进行烘焙：
+
+```tsx
+import { extractStyle } from '@ant-design/static-style-extract';
+import { ConfigProvider } from 'antd';
+
+const cssText = extractStyle((node) => (
+  <ConfigProvider
+    theme={{
+      token: {
+        colorPrimary: 'red',
+      },
+    }}
+  >
+    {node}
+  </ConfigProvider>
+));
+```
+
+#### 混合主题
+
+如果你的项目中使用了混合主题，可以尝试通过以下方式进行烘焙：
+
+```tsx
+import { extractStyle } from '@ant-design/static-style-extract';
+import { ConfigProvider } from 'antd';
+
+const cssText = extractStyle((node) => (
+  <>
+    <ConfigProvider
+      theme={{
+        token: {
+          colorBgBase: 'green ',
+        },
+      }}
+    >
+      {node}
+    </ConfigProvider>
+    <ConfigProvider
+      theme={{
+        token: {
+          colorPrimary: 'blue',
+        },
+      }}
+    >
+      <ConfigProvider
+        theme={{
+          token: {
+            colorBgBase: 'red ',
+          },
+        }}
+      >
+        {node}
