+## メモ
+- アイコン: Google Material Icons https://fonts.google.com/icons (Weight:300, Grade:0, Optical size: 24px)
+
+## モジュール構成
+### モジュール一覧
+- `component` : コンポーネント
+  - `common` : 共通コンポーネント
+  - `scanner` : スキャナー 
+  - `viewer` : ビューワー
+- `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
+  - `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 (廃止予定)
+  - `search`: 検索画面
+- `model` : データモデルをまとめたモジュール
+- `processor` : プロセッサ（例: `DocumentProcessor` : ドキュメント処理（ドキュメントにページを追加したり更新したり）)
+- `shared`: 共有リソース
+  - `ui`: UI要素(Theme, Drawable, Colorなど)
+- `source` : ソース(DB/FileManagerなど)
+- `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)
+- `// 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:`)
