+npm install @devup-ui/rsbuild-plugin
+```

+After installing the plugin, you can use the plugin in your rsbuild project.
+
+```js
+// rsbuild.config.mjs
+
+import { defineConfig } from '@rsbuild/core';
+import { pluginReact } from '@rsbuild/plugin-react';
+import { DevupUIRsbuildPlugin } from '@devup-ui/rsbuild-plugin';
+
+export default defineConfig({
+  plugins: [pluginReact(), DevupUIRsbuildPlugin()],
+});
+
+````
