About GitHub Pages and Jekyll

Jekyll is a static site generator with built-in support for GitHub Pages.

GitHub Pagesは、GitHub Free及びOrganizationのGitHub Freeのパブリックリポジトリ、GitHub Pro、GitHub Team、GitHub Enterprise Cloud、GitHub Enterprise Serverのパブリック及びプライベートリポジトリで利用できます。

About Jekyll

Jekyll is a static site generator with built-in support for GitHub Pages and a simplified build process. Jekyll takes Markdown and HTML files and creates a complete static website based on your choice of layouts. Jekyll supports Markdown and Liquid, a templating language that loads dynamic content on your site. For more information, see Jekyll.

Jekyll is not officially supported for Windows. For more information, see "Jekyll on Windows" in the Jekyll documentation.

We recommend using Jekyll with GitHub Pages. If you prefer, you can use other static site generators or customize your own build process locally or on another server. For more information, see "About GitHub Pages."

Configuring Jekyll in your GitHub Pages site

You can configure most Jekyll settings, such as your site's theme and plugins, by editing your _config.yml file. For more information, see "Configuration" in the Jekyll documentation.

Some configuration settings cannot be changed for GitHub Pages sites.

lsi: false
safe: true
source: [your repo's top level directory]
incremental: false
highlighter: rouge
  noscript: false
  math_engine: mathjax
  syntax_highlighter: rouge

By default, Jekyll doesn't build files or folders that:

  • are located in a folder called /node_modules or /vendor
  • start with _, ., or #
  • end with ~
  • are excluded by the exclude setting in your configuration file

If you want Jekyll to process any of these files, you can use the include setting in your configuration file.

Front matter

サイト上のページやポストに対してタイトルやレイアウトといった変数やメタデータを設定するには、任意のMarkdownあるいはHTMLファイルの先� �にYAMLフロントマターを追� できます。 詳しい情� �についてはJekyllのドキュメンテーション内の「フロントマター」を参照してく� さい。

You can add site.github to a post or page to add any repository references metadata to your site. For more information, see "Using site.github" in the Jekyll Metadata documentation.


JekyllのテーマをGitHub Pagesサイトに追� して、サイトのルックアンドフィールをカスタマイズできます。 For more information, see "Themes" in the Jekyll documentation.

You can add a theme to your site manually. For more information, see "Supported themes" on the GitHub Pages site and "Adding a theme to your GitHub Pages site using Jekyll."

You can override any of your theme's defaults by editing the theme's files. For more information, see your theme's documentation and "Overriding your theme's defaults" in the Jekyll documentation.


You can download or create Jekyll plugins to extend the functionality of Jekyll for your site. For example, the jemoji plugin lets you use GitHub-flavored emoji in any page on your site the same way you would on GitHub. For more information, see "Plugins" in the Jekyll documentation.

GitHub Pages uses plugins that are enabled by default and cannot be disabled:

You can enable additional plugins by adding the plugin's gem to the plugins setting in your _config.yml file. For more information, see "Configuration" in the Jekyll documentation.

For a list of supported plugins, see "Dependency versions" on the GitHub Pages site. For usage information for a specific plugin, see the plugin's documentation.

Tip: You can make sure you're using the latest version of all plugins by keeping the GitHub Pages gem updated. For more information, see "Testing your GitHub Pages site locally with Jekyll" and "Dependency versions" on the GitHub Pages site.

GitHub Pages cannot build sites using unsupported plugins. If you want to use unsupported plugins, generate your site locally and then push your site's static files to GitHub Enterprise Server.

Syntax highlighting

To make your site easier to read, code snippets are highlighted on GitHub Pages sites the same way they're highlighted on GitHub Enterprise Server. For more information about syntax highlighting on GitHub Enterprise Server, see "Creating and highlighting code blocks."

By default, code blocks on your site will be highlighted by Jekyll. Jekyll uses the Rouge highlighter, which is compatible with Pygments. Pygments has been deprecated and not supported in Jekyll 4. If you specify Pygments in your _config.yml file, Rouge will be used as the fallback instead. Jekyll cannot use any other syntax highlighter, and you'll get a page build warning if you specify another syntax highlighter in your _config.yml file. For more information, see "About Jekyll build errors for GitHub Pages sites."

If you want to use another highlighter, such as highlight.js, you must disable Jekyll's syntax highlighting by updating your project's _config.yml file.

    disable : true

If your theme doesn't include CSS for syntax highlighting, you can generate GitHub's syntax highlighting CSS and add it to your project's style.css file.

$ rougify style github > style.css

Building your site locally

変更がサイトの公開ソースにマージされると、サイトへの変更は自動的に公開されます。 まず変更をプレビューしたいなら、GitHub Enterprise Serverではなくローカルで変更を行えます。 そしてサイトをローカルでテストしてく� さい。 詳しい情� �については、「Jekyll を使用して GitHub Pages サイトをローカルでテストする」を参照してく� さい。
