Jekyll allows you to concoct your sites in any way you can dream up, and it’s thanks to the powerful and flexible configuration options that this is possible. These options can either be specified in a _config.yml file placed in your site’s root directory, or can be specified as flags for the jekyll executable in the terminal.

For technical reasons, _config.yml is NOT reloaded automatically when you use jekyll serve. If you change this file, please restart the server process.

Site Settings


If you’re using the Ruby gem version of the theme you’ll need this line to activate it:

theme: jekyll-text-theme

Color Theme

You can choose these 6 built-in color themes below:

default dark forest

The base hostname and protocol for your site. if you are hosting the site on Github Pages this will be set as the GitHub Pages domain (cname or user domain)1. For example, or if there is cname file.

Jekyll 3.3 overrides this value with url: http://localhost:4000 when running jekyll serve in a development environment2. You can specifying Jekyll environment3 to production environment by JEKYLL_ENV=production to avoid this behavior.

In order for jekyll-github-metadata to know what metadata to fetch it must be able to determine the repository NWO to ask GitHub about.

“NWO” stands for “name with owner.” It is GitHub lingo for the username of the owner of the repository plus a forward slash plus the name of the repository, e.g. ‘kitian616/jekyll-TeXt-theme’, where ‘kitian616’ is the owner and ‘jekyll-TeXt-theme’ is the repository name.

repository: username/repo-name
