 Jekyll is a simple, blog-aware, static site generator perfect for personal, project, or organization sites. Think of it like a file-based CMS, without all the complexity. Jekyll takes your content, renders Markdown and Liquid templates, and spits out a complete, static website ready to be served by Apache, Nginx or another web server. Jekyll is the engine behind [GitHub Pages](http://pages.github.com), which you can use to host sites right from your GitHub repositories.

 Jekyll does what you tell it to do — no more, no less. It doesn't try to outsmart users by making bold assumptions, nor does it burden them with needless complexity and configuration. Put simply, Jekyll gets out of your way and allows you to concentrate on what truly matters: your content.

-コントリビュート
-==========
-
-あなたは Jekyll に投じるすばらしいアイディアを持っています。
-すばらしいことです！次の事柄を心に留めてください。
-
-* **テストなしではコントリビュートはできません。**
-* もし、既存の機能への小さな修正やパッチを作成したなら、シンプルなテストを行います。
-  現在のテストスイートの範囲にとどまり、そして
-  [Shoulda](https://github.com/thoughtbot/shoulda/tree/master) や
-  [RR](https://github.com/btakita/rr/tree/master) を使用してください。
-* もし、それが新しい機能の場合は、必ず新しい
-  [Cucumber](https://github.com/cucumber/cucumber/) の機能を作成し、
-  必要に応じて手順を再利用します。
-  また、あなたがフォークした `site` に
-  急ぎいくつかのドキュメントを用意し、一度マージを行い
-  メイン `site` の jekyllrb.com に転送していただければ幸いです。
-* あなたのコントリビュートによって Jekyll の振る舞いが変わった場合、ドキュメントを更新すべきです。
-  それは `site/docs` にあります。
-  もし、 docs に情報の誤りがあった場合、遠慮なく追加してください。
-  すばらしいドキュメントはすばらしいプロジェクトを作ります！
-* Ruby のコードを変更するときは、 [GitHub Ruby Styleguide](https://github.com/styleguide/ruby)
-  に従ってください。
-* **小さなプルリクエスト** に最善を尽くしてください。
-  簡単に提案された変更はレビューされ、マージされる可能性が高いです。
-* プルリクエストを送信するとき、プルリクエストのボディを賢明に使用してください。
-  変更されたかどうかの記述、変更の背後にある動機、 [完了したかどうかのタスクリスト](http://git.io/gfm-tasks)
-  もレビュー時間を早めます。
-
-テストの依存関係
------------------
-
-テストスイートの実行や gem のビルドのために、
-Jekyll の依存ツールをインストールする必要があります。
-Jekyll は Bundler を使用しており、 `bundle` コマンドを実行すると全ての設定が迅速に行われます！
-
-    $ bundle
-
-はじめる前に、テストを実行し、必ずテストが通ることを
-確認してください(あなたの環境が適切に設定されているかを確認するために):
-
-    $ bundle exec rake test
-    $ bundle exec rake features
-
-ワークフロー
---------
-
-これは、あなたの作業がプロジェクトにマージされるもっとも直接的な方法です:
-
-* プロジェクトをフォークします。
-* あなたのフォークプロジェクトをクローンします ( `git clone git@github.com:<username>/jekyll.git` )。
-* トピックブランチを作成し、あなたの変更を含んでください ( `git checkout -b my_awesome_feature` )。
-* ハックし、テストを追加します。必ずしもこの順番でなくてかまいません
-* `rake` を実行し、テストが必ず全て通ることを確認してください
-* 必要に応じて、エラーがないようにコミットを論理的な塊にリベースしてください
-* ブランチをプッシュしてください ( `git push origin my_awesome_feature` ).
-* jekyll/jekyll プロジェクトの master ブランチに対してプルリクエストを作成し、
-  あなたの変更内容と、なぜそれをマージすべきかを記述してください
-
-ドキュメントの更新
-----------------------
-
-私たちは Jekyll のドキュメントについて最善を尽くしたいです。
-私たちはドキュメントをオープンソース化しました、そして
-あなたが Jekyll に欠けているものを見つけた場合、私たちはプルリクエストを歓迎しています。
-
-あなたは、 GitHub.com 上の Jekyll リポジトリの [site]({{ site.repository }}/tree/master/site) で
-jekyllrb.comのドキュメントを見つけることができます。
-
-全てのドキュメントのプルリクエストは `master` に向けられる必要があります。
-他のブランチに向けたプルリクエストは受け入れられません。
-
-GitHub の [Jekyll wiki](https://github.com/jekyll/jekyll/wiki) は、
-自由に更新することができるように、プルリクエストなしで
-全ての GitHub ユーザがアクセス権を持つことができます。
-
-落とし穴
--------
-
-* もし、 gem のバージョンがかちあった場合、コミットを分けてください。
-  この方法だと、メンテナが gem をリリースするときに制御できます。
-* jekyll/jekyll の最新コミットに基づいて(複数の)パッチを維持してください。
-  それは適用するためのあなたの仕事で、メンテナがしなければならないことを少なくするのは
-  とてもよいことです。
-* あなたの GitHub issue で [fix], [feature] などのタグをつけないでください。
-  メンテナは積極的に issue を読み、彼らが問題に出くわしたらラベルをつけるでしょう。
-
-最後に…
-----------
-
-ありがとう！ Jekyll のハックは楽しいものでなければなりません。
-もし、あなたがこのハードを理解するための何かを発見した場合、知らせてください。
-我々のプロセスやドキュメントを改善することができます！

-
-Jekyll は個人プロジェクトや組織のサイトに最適な、シンプルで、ブログを意識した静的サイトジェネレータです。
-複雑さを排除したファイルベースのCMSのようなものと考えてください。
-Jekyll はコンテンツを受け取り、 Markdown や Liquid テンプレート をレンダリングし、
-Apache や Nginx やその他の Web サーバに提供する準備ができた静的な Web サイトを完全に出力してくれます。
-Jekyll は [GitHub Pages](http://pages.github.com) の背後にあるエンジンなので、
-あなたの GitHub リポジトリからサイトをホストするために使用する事ができます。
-
-## 原理
-
-Jekyll あなたがするように伝えたことをします ― それ以上でもそれ以下でもありません。
-それは、大胆な仮定によってユーザの裏をかこうとせず、
-また、不必要な複雑さや設定をユーザに負担しません。
-簡単に言えば、 Jekyll はあなたの道を開け、
-真に重要なもの: コンテンツに集中することができます。
-
-## 開始方法
-
-* gem を[インストール](http://jekyllrb.com/docs/installation/)します
-* [使用方法](http://jekyllrb.com/docs/usage/) と [設定方法](http://jekyllrb.com/docs/configuration/) を読みます
-* 既存の [Jekyll で作られたサイト](https://wiki.github.com/jekyll/jekyll/sites) をチラッと見ます
-* Fork し、あなたの変更を [コントリビュート](http://jekyllrb.com/docs/contributing/) します
-* 質問があったら？ irc.freenode.net の `#jekyll` チャンネルをチェックしてください
-
-## より深く
-
-* 以前のシステムからの[移行](http://jekyllrb.com/docs/migrations/)
-* [YAML Front Matter](http://jekyllrb.com/docs/frontmatter/) がどのように働くかを学ぶ
-* [変数](http://jekyllrb.com/docs/variables/)を使ってサイトに情報を表示する
-* posts が生成される時の[パーマリンク](http://jekyllrb.com/docs/permalinks/)をカスタマイズ
-* 人生を容易にするために、組み込みの [Liquid 拡張](http://jekyllrb.com/docs/templates/)を使用する
-* あなたのサイト固有のコンテンツを生成するために、カスタム[プラグイン](http://jekyllrb.com/docs/plugins/)を使用する
