 # @rsbuild/plugin-vue2-jsx
 
-@rsbuild/plugin-vue2-jsx is a Rsbuild plugin to do something.
+Provides support for Vue 2 JSX / TSX syntax. The plugin internally integrates [@vue/babel-preset-jsx](https://github.com/vuejs/jsx-vue2).

 ```ts
 // rsbuild.config.ts
+import { pluginBabel } from "@rsbuild/plugin-babel";
+import { pluginVue2 } from "@rsbuild/plugin-vue2";
 import { pluginVue2Jsx } from "@rsbuild/plugin-vue2-jsx";
 
 export default {
-  plugins: [pluginVue2Jsx()],
+  plugins: [
+    pluginBabel({
+      include: /\.(?:jsx|tsx)$/,
+    }),
+    pluginVue2(),
+    pluginVue2Jsx(),
+  ],
 };
 ```
 
+Since the Vue JSX plugin relies on Babel for compilation, you need to additionally add the [@rsbuild/plugin-babel](https://www.npmjs.com/package/@rsbuild/plugin-babel).
+
+Babel compilation will introduce extra overhead, in the example above, we use `include` to match `.jsx` and `.tsx` files, thereby reducing the performance cost brought by Babel.
+
+After registering the plugin, you can use Vue's [JSX / TSX syntax](https://github.com/vuejs/jsx-vue2) in `.jsx`, `.tsx`, and `.vue` files.
+
+## Vue SFC
+
+When using JSX in Vue SFC, you need to add `lang="jsx"` or `lang="tsx"` to the `<script>` tag.
+
+- JSX:
+
+```html title="App.vue"
+<script lang="jsx">
+  const vnode = <div>hello</div>;
+</script>
+```
+
+- TSX:
+
+```html title="App.vue"
+<script lang="tsx">
+  const vnode = <div>hello</div>;
+</script>
+```
+
 ## Options
 
-### foo
+If you need to customize the compilation behavior of Vue JSX, you can use the following configs.
+
+### vueJsxOptions
 
-Some description.
