 # Lacerta
 WIP
+## モジュール設計
+
+![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
+    - UIの中で共通で使う要素(メニューアイテムとか)
+  - `scanner` : スキャナー
+    - スキャナーの実装
+  - `viewer` : ビューワー
+    - ドキュメントビューワーの実装
+- `data` : データ
+  - 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
+  - `Document` : ドキュメント関係
+    - WIP(JavaDocを参照してください, 余裕があったら追記します)
+- `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
+  - `search`: 検索画面
+- `model` : モデル
+  - データモデルをまとめたモジュール (WIP)
+  - `document` : ドキュメント
+  - `meta` : メタデータ
+- `processor` : プロセッサ
+  - いくつかの処理をまとめたモジュール
+    - `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
+- `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
+  - `LacertaLogger` : ロガー
+  - `XmlMetaParser` : XMLメタデータパーサー(フロントから直接操作することは絶対にありません)
+
+
+## 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)
