+Note that relay implements :code:`pagination` capabilities automatically, adding a :code:`pageInfo` element, and including :code:`cursor` on nodes. These elements are included in the above example for illustration.

+To learn more about Pagination in general, take a look at `Pagination <https://graphql.org/learn/pagination/>`__  on the GraphQL community site.
