-The UI is designed to be efficient and easy to maintain by using atomic design, subdividing components, and designing reusable modules. Atomic design is recommended for UI construction, and the segmentation of components, reusable module design, and other features enable efficient UI construction and maintenance. \
-[Framework Features](https://next2d.app/#framework)
+### 日本語
+従来のCanvas/WebGL/WebGPUアプリケーションでは困難だったURLによるシーン管理（SPA）を可能にし、シーン毎のUI開発・画面確認が可能になりました。UI構築にはアトミックデザインを推奨しており、コンポーネントの細分化、再利用可能なモジュール設計など、効率的なUI構築と保守が可能となっています。 \
+
+### English
+URL-based scene management (SPA) is now possible, which was difficult with traditional Canvas/WebGL/WebGPU applications, enabling UI development and screen verification for each scene. Atomic Design is recommended for UI construction, allowing efficient UI building and maintenance through component granularity and reusable module design. \
