   You can set default values for YAML parameters in the config file. Open the `_config.yml` file, scroll down to the line `defaults:` and that's the section you can use. For more information, see the [official jekyll documentation about default values](https://jekyllrb.com/docs/configuration/front-matter-defaults/).
