 Settings that affect your entire site can be changed in [Jekyll's configuration file](https://jekyllrb.com/docs/configuration/): `_config.yml`, found in the root of your project. If you don't have this file you'll need to copy or create one using the theme's [default `_config.yml`](https://github.com/mmistakes/minimal-mistakes/blob/master/_config.yml) as a base.
