-
-# This key contains most of the YAML anchors that will be used later in the

-# YAML anchors work by defining an anchor with `&anchor-name` and reusing its
-# content in another place with `*anchor-name`. The special `<<` map key merges
-# the content of the map with the content of the anchor (or list of anchors).
