Jekyll use config.yml values in the HTML

Question

Is it possible to setup configuration values within the config.yml file and have them be printed within the HTML page within Jekyll? I would like to set the default title and description of my website within the config.yml file and have them printed out in the header of all my layouts.

Answer 1

Every template has a site variable, which contains the settings from _config.yml. For example, if you have something like my_setting: "string" in _config.yml, you can access the value in a template using {{ site.my_setting }}.

Note: if you are using jekyll serve, you will need to restart the process for changes to take place. Indeed, _config.yml is not reloaded with the watch option.
