 # renovate-config
 
-Renovate Configuration.
+このリポジトリには、依存関係の更新ツールであるRenovateの設定ファイルが含まれています。Renovateは、プロジェクトの依存関係を最新のバージョンに保つプロセスを自動化するのに役立ちます。
+
+## 参照する仕組み
+
+```mermaid
+graph LR
+A[リポジトリ] -- 参照 --> B[renovate.json]
+B -- 参照 --> C[tqer39/renovate-config/default.json]
+C -- 参照 --> C[tqer39/renovate-config/*.json]
+```
+
+## 動作方法
+
+1. このリポジトリを自分のGitHubアカウントにフォークします。
+2. プロジェクトの要件に基づいて、必要な変更を設定ファイルに行います。
+3. Renovateを設定して、フォークしたリポジトリを設定のソースとして使用します。
+4. Renovateは定期的にプロジェクトの依存関係をスキャンし、このリポジトリの設定に基づいて最新バージョンに更新するためのプルリクエストを作成します。
+
+## 貢献
+
+設定ファイルに対する提案や改善点がある場合は、問題を開いたりプルリクエストを送信したりしてください。
+
+更新を楽しんでください！
