Adding Jekyll plugins to a GitHub Pages site
GitHub Pages is available in public repositories with GitHub Free, and in public and private repositories with GitHub Pro, GitHub Team, GitHub Enterprise Cloud, and GitHub Enterprise Server. For more information, see "GitHub's products."
You can further customize your GitHub Pages site by adding Jekyll plugins.
Configuring Jekyll plugins
You must edit your _config.yml file to add Jekyll plugins to your GitHub Pages site.
Sitemaps for GitHub Pages
GitHub Pages can automatically create sitemaps for your projects.
Search engine optimization for GitHub Pages
GitHub Pages can optimize your site for search engines and social media networks, using the Jekyll SEO tag plugin.
Repository metadata on GitHub Pages
Common repository information, such as the project name and description, is available to Jekyll sites hosted on GitHub Pages.
Atom (RSS) feeds for GitHub Pages
GitHub Pages can automatically create an Atom feed for your Jekyll blog. Atom is an XML-based feed format, similar to RSS, that allows other readers to subscribe to new blog posts.
Redirects on GitHub Pages
When a Jekyll post or page's title or date changes, existing links to the site may break. For the security of our users, GitHub Pages does not support customer server configuration files such as
.conf. However, using the Jekyll Redirect From plugin, you can automatically redirect visitors to the updated URL.
Emoji on GitHub Pages
You can use emoji within any Jekyll page or post, just like you would in a comment or issue within a repository on GitHub.
"@Mentions on GitHub Pages"
You can use @mentions within any Jekyll page or post, just like you would in a comment or issue within a repository.
