 # Lacerta
-WIP
+学習に便利な機能とGit-like VCSを持ったドキュメントスキャナ (Work In Progress)
+(グループワーク)
+
 ## モジュール設計
+![Untitled Diagram(2)(1) drawio(1)](https://github.com/lacerta-doc/Lacerta/assets/66072112/f9b9c40f-bed0-4ade-95c1-50e28df68f35)
 
-![Untitled Diagram(2)](https://github.com/lacerta-doc/Lacerta/assets/66072112/9daabaca-5cdc-49f8-ac66-196c588a47c9)
 
 ## 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)
-### 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)
