A year after Jekyll sites on GitHub Pages gained access to repository and organization metadata through the site.github namespace, GitHub has transitioned to using the community-driven GitHub metadata Jekyll plugin. This change simplifies the process of previewing sites locally by allowing users to replicate the exact same build process GitHub Pages uses in production. To achieve this, users need to add the jekyll-github-metadata gem to their site's configuration if they are using the GitHub Pages gem. Additional details and guidance on using repository and organization metadata are available in the plugin and repository metadata documentation.
