ansible playbook for my gnome setup
# https://docs.ansible.com/ansible/latest/modules/dconf_module.html

# To determine what dconf keys and values to use, you can run `dconf watch /`
# in a terminal as you make changes in settings or tweaks. You can also use
# `dconf read <key>` and `dconf write <key> <value>` to experiment with various
# settings. The dconf-editor application is also useful for exploring various
# keys along with their descriptions.
