+Contribute
+==========
+
+So you've got an awesome idea to throw into Jekyll. Great! Please keep the
+following in mind:
+
+* **Contributions will not be accepted without tests or necessary documentation updates.**
+* If you're creating a small fix or patch to an existing feature, just a simple
+  test will do. Please stay in the confines of the current test suite and use
+  [Shoulda](https://github.com/thoughtbot/shoulda/tree/master) and
+  [RR](https://github.com/rr/rr).
+* If it's a brand new feature, make sure to create a new
+  [Cucumber](https://github.com/cucumber/cucumber/) feature and reuse steps
+  where appropriate. Also, whipping up some documentation in your fork's `site`
+  would be appreciated, and once merged it will be transferred over to the main
+  `site`, jekyllrb.com.
+* If your contribution changes any Jekyll behavior, make sure to update the
+  documentation. It lives in `site/docs`. If the docs are missing information,
+  please feel free to add it in. Great docs make a great project!
+* Please follow the [GitHub Ruby Styleguide](https://github.com/styleguide/ruby)
+  when modifying Ruby code.
+* Please do your best to submit **small pull requests**. The easier the proposed
+  change is to review, the more likely it will be merged.
+* When submitting a pull request, please make judicious use of the pull request
+  body. A description of what changes were made, the motivations behind the
+  changes and [any tasks completed or left to complete](http://git.io/gfm-tasks)
+  will also speed up review time.
+
+Test Dependencies
+-----------------
+
+To run the test suite and build the gem you'll need to install Jekyll's
+dependencies. Jekyll uses Bundler, so a quick run of the bundle command and
+you're all set!
+
+    $ bundle
+
+Before you start, run the tests and make sure that they pass (to confirm your
+environment is configured properly):
+
+    $ bundle exec rake test
+    $ bundle exec rake features
+
+Workflow
+--------
+
+Here's the most direct way to get your work merged into the project:
+
+* Fork the project.
+* Clone down your fork ( `git clone git@github.com:<username>/jekyll.git` ).
+* Create a topic branch to contain your change ( `git checkout -b my_awesome_feature` ).
+* Hack away, add tests. Not necessarily in that order.
+* Make sure everything still passes by running `rake`.
+* If necessary, rebase your commits into logical chunks, without errors.
+* Push the branch up ( `git push origin my_awesome_feature` ).
+* Create a pull request against jekyll/jekyll and describe what your change
+  does and the why you think it should be merged.
+
+Updating Documentation
+----------------------
+
+We want the Jekyll documentation to be the best it can be. We've
+open-sourced our docs and we welcome any pull requests if you find it
+lacking.
+
+You can find the documentation for jekyllrb.com in the
+[site](https://github.com/jekyll/jekyll/tree/master/site) directory of
+Jekyll's repo on GitHub.com.
+
+All documentation pull requests should be directed at `master`.  Pull
+requests directed at another branch will not be accepted.
+
+The [Jekyll wiki](https://github.com/jekyll/jekyll/wiki) on GitHub
+can be freely updated without a pull request as all GitHub users have access.
+
+Gotchas
+-------
+
+* If you want to bump the gem version, please put that in a separate commit.
+  This way, the maintainers can control when the gem gets released.
+* Try to keep your patch(es) based from the latest commit on jekyll/jekyll.
+  The easier it is to apply your work, the less work the maintainers have to do,
+  which is always a good thing.
+* Please don't tag your GitHub issue with [fix], [feature], etc. The maintainers
+  actively read the issues and will label it once they come across it.
+
+Finally...
+----------
+
+Thanks! Hacking on Jekyll should be fun. If you find any of this hard to figure
+out, let us know so we can improve our process or documentation!

+
+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.
+
+## Philosophy
+
+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.
+
+## Getting Started
+
+* [Install](http://jekyllrb.com/docs/installation/) the gem
+* Read up about its [Usage](http://jekyllrb.com/docs/usage/) and [Configuration](http://jekyllrb.com/docs/configuration/)
+* Take a gander at some existing [Sites](https://wiki.github.com/jekyll/jekyll/sites)
+* Fork and [Contribute](http://jekyllrb.com/docs/contributing/) your own modifications
+* Have questions? Check out [`#jekyll` on irc.freenode.net](https://botbot.me/freenode/jekyll/).
+
+## Diving In
+
+* [Migrate](http://import.jekyllrb.com/docs/home/) from your previous system
+* Learn how the [YAML Front Matter](http://jekyllrb.com/docs/frontmatter/) works
+* Put information on your site with [Variables](http://jekyllrb.com/docs/variables/)
+* Customize the [Permalinks](http://jekyllrb.com/docs/permalinks/) your posts are generated with
+* Use the built-in [Liquid Extensions](http://jekyllrb.com/docs/templates/) to make your life easier
+* Use custom [Plugins](http://jekyllrb.com/docs/plugins/) to generate content specific to your site

+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！

+Tom Preston-Werner, Nick Quaranto や多くの[素晴らしいコントリビュータ](https://github.com/jekyll/jekyll/graphs/contributors)によって作成されています！
+
+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
+
+## 実行時の依存関係
+
+* Commander: コマンドラインインターフェース構築 (Ruby)
+* Colorator: コマンドライン出力に色付け (Ruby)
+* Classifier: posts の関連を生成 (Ruby)
+* Directory Watcher: サイトの自動再生成 (Ruby)

+You'll find this post in your `_posts` directory - edit this post and re-build (or run with the `-w` switch) to see your changes!
+To add new posts, simply add a file in the `_posts` directory that follows the convention: YYYY-MM-DD-name-of-post.ext.
+
+Jekyll also offers powerful support for code snippets:
+
+{% highlight ruby %}
+def print_hi(name)
+  puts "Hi, #{name}"
+end
+print_hi('Tom')
+#=> prints 'Hi, Tom' to STDOUT.
+{% endhighlight %}
