-    - WIP(JavaDocを参照してください, 余裕があったら追記します)
+- `data` : UIからデータを取得/保存するためのラッパーモジュール
 - `feature` : 機能モジュール(ナビゲーションからみた機能で分割)
   - `common`: 共通機能
-    - 設定画面とか、どこからでも呼ばれうる画面
   - `debug`: デバッグメニュー
   - `home`: ホーム画面
   - `library`: ライブラリ画面
-  - `scan`: スキャン画面
+  - `scan`: スキャン画面 (廃止予定)

-- `shared` : 
-  - 共有リソース
-- `source` : ソース
-  - (バックエンドが使うのでとりあえず後回し、フロントから直接操作することは絶対にありません)
-- `utils` : ユーティリティ
-  - ちょっとしたユーティリティをまとめたモジュール

+- `utils` : ユーティリティ(ちょっとしたユーティリティをまとめたモジュール)
 
 ## コーディング規則/推奨(WIP)
-### 規則
 - `// TODO`コメントには任意のsuffixを付ける
   - 全員が同じ`// TODO:`を使っていると検索がむずかしくなるため
   - (例: `// TODO-rca:`)
-### 推奨
-- マジックナンバーは控える(必要な場合もあるので)
