You can configure most Jekyll settings by editing your _config.yml file.
Note: For more information on configuring your site with Jekyll, see the official Jekyll configuration documentation.
Defaults you can change
The following defaults are set by GitHub, which you are free to override in your _config.yml file:
github: [metadata] kramdown: input: GFM hard_wrap: false gems: - jekyll-coffeescript - jekyll-paginate
Configuration settings you cannot change
GitHub Pages & Jekyll override the following settings in your _config.yml file, which you cannot change:
lsi: false safe: true source: [your repo's top level directory] incremental: false highlighter: rouge gist: noscript: false kramdown: math_engine: mathjax
For the content of the repository metadata object, see repository metadata on GitHub Pages.
Keep in mind that if you change the
sourcesetting, your pages may not build correctly. GitHub Pages only considers source files in the top-level directory of a repository.
Front matter is required
Jekyll requires that Markdown files have front matter defined at the top of every file. Front matter is just a set of metadata, delineated by three dashes:
--- title: This is my title layout: post --- Here is my page.
If you like, you can choose to omit front matter from your file, but you'll still need to make the triple-dashes:
--- --- Here is my page.
If your file is within the _posts directory, you can omit the dashes entirely.
For more information on configuring the front matter, see the official Jekyll front matter documentation.
