+[^yaml-anchors]: `en-US`, and `en-GB` use [YAML anchors](http://www.yaml.org/spec/1.2/spec.html#id2785586) to reference the values in `en` as to not repeat them.
 
 Many of the label based keys like `meta_label`, `categories_label`, `tags_label`, `share_on_label`, and `follow_label` can be left blank if you'd like to omit them from view. It really depends on you and if you want an even more minimal look to your site.
