 # Vuetify TSX
 
+Vuetify TSX is just a wrapper lib around vuetify components.
+This lib use `vue-tsx-support` under the hood to support TSX (JSX for TypeScript).
+
 ## Setup
 
 ```bash
 npm install vuetify-tsx
 ```
 
+## Usage
+
+```tsx
+import { component } from 'vue-tsx-support';
+import { VApp, VContent } from 'vuetify-tsx';
+
+export default component({
+  name: 'Default',
+  render() {
+    return (
+      <VApp>
+        <VContent>
+          <nuxt />
+        </VContent>
+      </VApp>
+    );
+  },
+});
+```
+
+## Tip
+
+Use `babel-plugin-import` to reduce bundle size.
+
+```js
+{
+  plugins: [
+    [
+      'import',
+      {
+        libraryName: 'vuetify-tsx',
+        libraryDirectory: 'lib',
+        camel2DashComponentName: false,
+      },
+    ],
+  ],
+}
+```
