 You can define variables that relate to a specific host or group in inventory. A simple way to start is by adding variables directly to the hosts and groups in a YAML or INI inventory source.
 
-We document adding variables in the inventory source for simplicity. However, you can also use :ref:`vars_plugins` to add variables from many other sources, Ansible, by default, ships with the :ref:`host_group_vars <host_group_vars_vars>` plugin, which allows defining variables in separate host and group variable files. This is a more robust approach to describing your system policy. Setting variables in the inventory source is only one way to do it. See :ref:`splitting_out_vars` for guidelines on storing variable values in individual files in the 'host_vars' and 'group_vars' directories. See :ref:`splitting_out_vars` for details.
