+# Pengenalan
+
+Design patterns adalah best practice yang dapat digunakan programmer untuk memecahkan masalah umum saat merancang aplikasi atau sistem.
+
+Design patterns dapat mempercepat proses pengembangan dengan menyediakan kode yang teruji, terbukti paradigma pengembangan.
+
+Menggunakan kembali design patterns membantu mencegah masalah-masalah kecil yang dapat menyebabkan masalah yang lebih besar, dan juga meningkatkan keterbacaan kode untuk programmer dan arsitek yang
+familiar dengan pola.
+
+
+# Mulai
+
+Situs ini menampilkan Design Patterns pada Java. Solusi-solusi yang terdapat pada situs ini telah dikembangkan oleh programmer dan arsitek  yang berpengalaman dari komunitas open source. Pola-polanya dapat dilihat pada deskripsi atau dengan melihat source code mereka. Contoh-contoh source code memiliki komentar yang baik dan dapat dianggap sebagai tutorial pemrograman tentang cara menerapkan pola tertentu. Kami menggunakan teknologi Java open source yang populer dan telah terbukti.
+
+Sebelum anda masuk kedalam materinya, anda harus familiar dengan macam-macam [Software Design Principles](https://java-design-patterns.com/principles/).
+
+Semua desain seharusnya sesimpel mungkin. Anda harus mulai dengan KISS, YAGNI, dan prinsip Do The Simples Thing That Could Possibly Work. hanya boleh diperkenalkan ketika dibutuhkan untuk praktik
+kemungkinan diperpanjang.
+
+Setelah Anda terbiasa dengan konsep-konsep ini, Anda dapat mulai belajar
+[design patterns yang tersedia](https://java-design-patterns.com/patterns/) menggunakan cara-cara berikut
+
+ - Cari spesifik pattern berdasarkan namanya. Apabila tidak menemukannya tolong lapor pattern baru [disini](https://github.com/iluwatar/java-design-patterns/issues).
+ - Gunakan tag-tag seperti `Performance`, `Gang of Four` atau `Data access`.
+ - Gunakan kategori dari pattern, `Creational`, `Behavioral`, dan sebagainya.
+
+Semoga Anda menemukan solusi Object-Oriented yang bermanfaat untuk arsitektur Anda dari yang disajikan di situs ini dan mempelajarinya dengan senang seperti kami mengembangkannya.
+
+# Cara berkontribusi

+# Введение
+Шаблоны проектирования - лучший метод для решения проблем, возникающих
+во время разработки приложения или системы.
+
+Шаблоны проектирования могут ускорить процесс разработку путем предоставления
+проверенных моделей/парадигм.
+
+Использование шаблонов повторно поможет избежать частых проблем, из-за которых
+происходят проблемы. А еще это повысит читаемость кода для программистов и 
+архитекторов, знакомых с шаблонами.
+
+# Начало работы
+
+В этом репозитории размещены шаблоны проектирования на Java. Они были разработаны
+программистами из open source сообщества. Шаблон может быть выбран 
+из его описания или просмотром его исходного кода. Код хорошо задокументирован,
+его можно рассматривать, как учебник по программированию о конкретном шаблоне.
+Мы используем самые популярные (прошедшие огонь, воду и медные трубы) технологии,
+основанные только на ПО с открытым исходным кодом.
+
+Преждем чем нырнуть в материал, тебе следует ознакомиться с различными
+[принципами разработки ПО(англ)](https://java-design-patterns.com/principles/).
+
+Все конструкции должны быть максимально простыми. Не делай лишнюю функциональность,
+которая скорей всего не пригодиться, а просто создай простую штуку, что сможет
+работать. Усложнять и вводить паттерны необходимо, лишь когда масштабируемость
+действительно нужна.
+
+Как только ознакомитесь с этими концепциями, приступайте к изучению
+[доступных шаблонов проектирования(англ)](https://java-design-patterns.com/patterns/) любым
+из следующих методов:
+
+- Ищите шаблон по имени. Не смогли найти такой? Сообщите об этом [здесь](https://github.com/iluwatar/java-design-patterns/issues).
+- Используя тэги, например `Performance`, `Gang of Four` или `Data access`.
+- Используя категории шаблонов `Creational`, `Behavioral` и другие.
+
+Надеемся объективно-ориентированные решения, представленные здесь будут вам 
+полезны и найдут место в ваших проектах, а также вы получите такое же удовольствие 
+от их изучения, какое получили мы во время их разработки.
+
+# Как принять участие в разработке
+
+Если вы захотите принять участие в жизни проекта, вся полезная информация находится на 
+нашей [вики(англ)](https://github.com/iluwatar/java-design-patterns/wiki). Мы можем помочь
+и ответить на твои вопросы в чате [Gitter](https://gitter.im/iluwatar/java-design-patterns).
