# Local development services.
#
# The development.services.yml file allows the developer to override
# container parameters for debugging.
#
# To activate this feature, follow the instructions at the top of the
# 'example.settings.local.php' file, which sits next to this file.
#
# Be aware that in Drupal's configuration system, all the files that
# provide container definitions are merged using a shallow merge approach
# within \Drupal\Core\DependencyInjection\YamlFileLoader.
# This means that if you want to override any value of a parameter, the
# whole parameter array needs to be copied from
# sites/default/default.services.yml or from core/core.services.yml file.
