@adriangonz Are you sure we still want to add pygmentize and tree? I am aware we use pygmentize in other examples but tbh for these small yaml files cat would do, and if we really want to print the directory in tree form you can use the crazy ls:

ls -R | grep ":$" | sed -e 's/:$//' -e 's/[^-][^\/]*\//--/g' -e 's/^/   /' -e 's/-/|/'
