-# はじめに
-
-デザインパターンとは、アプリケーションやシステムを設計する際によくある問題を解決するために、プログラマーが使用できる形式化された最良の手法です。
-
-デザインパターンは、テストされ、証明された開発パラダイムを提供することで、開発プロセスを高速化することができます。
-
-デザインパターンを再利用することで、大きな問題を引き起こす微妙な問題を防ぐことができます。
-また、デザインパターンを熟知したコーダーやアーキテクトにとっても、コードの読みやすさが向上します。
-
-# はじめる
-
-このサイトでは、Java のデザインパターンを紹介しています。
-これらのソリューションは、オープンソースコミュニティの経験豊富なプログラマーやアーキテクトによって開発されています。
-
-パターンは、ハイレベルの説明またはソースコードを確認することで参照できます。
-
-ソースコードの例はよくコメントされていて、特定のパターンをどのように実装するかを説明するプログラミングチュートリアルのようなものです。
-
-私たちは、最も一般的で実績のあるオープンソースの Java 技術を使用しています。
-
-資料に飛び込む前に、さまざまな[ソフトウェア設計の原則](https://java-design-patterns.com/principles/)に精通している必要があります。
-
-すべてのデザインは、可能な限りシンプルであるべきです。
-
-KISS(シンプルにしておけ!この間抜け)、YAGNI(機能は実際に必要となるまでは追加しないのがよい)、そして Do The Simplest Thing That Could Possibly Work(機能する可能性のある中で最もシンプルなことをする)の原則に基づいて設計を始めるべきです。
-
-複雑さやパターンは、実用的な拡張性が必要な場合にのみ導入すべきです。
-
-これらの概念を理解した上で、以下のような方法で[デザインパターン](https://java-design-patterns.com/patterns/) を掘り下げていくことができます。
-
-- 特定のパターンを、パターン名で検索することができます。見つかない場合は、新しいパターンを[ここ](https://github.com/iluwatar/java-design-patterns/issues)で報告してください
-- `Performance`, `Gang of Four` もしくは`Data access`などのタグを使用。
-- `Creational`, `Behavioral`などのパターンカテゴリーを使用。
-
-このサイトで紹介されているオブジェクト指向のソリューションが、あなたのアーキテクチャに役立ち、私たちが開発したように楽しく学ぶことができますように。
-
-# コントリビュート方法
-
-プロジェクトに貢献したいとお考えの方は、[開発者 wiki](https://github.com/iluwatar/java-design-patterns/wiki)に関連情報が掲載されています。

-私たちは、[Gitter チャットルーム](https://gitter.im/iluwatar/java-design-patterns)であなたの質問にお答えします。
