+需要将多代码块合并成一个分组进行展示时，可以使用 CodeGroup 语法，例如：
+
+```jsx
+/**
+ * inline: true
+ */
+import SourceCode from 'dumi/theme/builtins/SourceCode';
+const content = `
+:::code-group
+
+\`\`\`bash [npm]
+npm install -D dumi
+\`\`\`
+
+\`\`\`bash [yarn]
+yarn add -D dumi
+\`\`\`
+
+\`\`\`bash [pnpm]
+pnpm add -D dumi
+\`\`\`
+
+\`\`\`ts [.dumirc.ts] {3}
+import { defineConfig } from 'dumi';
+
+export default defineConfig({
+  // ...
+});
+\`\`\`
+:::
+`.trim();
+
+export default () => <SourceCode lang="markdown">{content}</SourceCode>;
+```
+
+将会被渲染为：
+
+:::code-group
+
+```bash [npm]
+npm install -D dumi
+```
+
+```bash [yarn]
+yarn add -D dumi
+```
+
+```bash [pnpm]
+pnpm add -D dumi
+```
+
+```ts [.dumirc.ts] {3}
+import { defineConfig } from 'dumi';
+
+export default defineConfig({
+  // ...
+});
