+  #
+  # Note: Aim for an image that's 21px high so it fits in the header.
+  #
+  # config.site_title_image = "logo.png"
+
+  # == Load Paths
+  #
+  # By default Active Admin files go inside app/admin/.
+  # You can change this directory.
+  #
+  # eg:
+  #   config.load_paths = [File.join(Rails.root, 'app', 'ui')]
+  #
+  # Or, you can also load more directories.
+  # Useful when setting namespaces with users that are not your main AdminUser entity.
+  #
+  # eg:
+  #   config.load_paths = [
+  #     File.join(Rails.root, 'app', 'admin'),
+  #     File.join(Rails.root, 'app', 'cashier')
+  #   ]
+
+  # == Default Namespace
+  #
+  # Set the default namespace each administration resource
+  # will be added to.
+  #
+  # eg:
+  #   config.default_namespace = :hello_world
+  #
+  # This will create resources in the HelloWorld module and
+  # will namespace routes to /hello_world/*
+  #
+  # To set no namespace by default, use:
+  #   config.default_namespace = false
+  #
+  # Default:
+  # config.default_namespace = :admin
+  #
+  # You can customize the settings for each namespace by using
+  # a namespace block. For example, to change the site title
+  # within a namespace:
+  #
+  #   config.namespace :admin do |admin|
+  #     admin.site_title = "Custom Admin Title"
+  #   end
+  #
+  # This will ONLY change the title for the admin section. Other
+  # namespaces will continue to use the main "site_title" configuration.
+
+  # == User Authentication
+  #
+  # Active Admin will automatically call an authentication
+  # method in a before filter of all controller actions to
+  # ensure that there is a currently logged in admin user.

+  # This setting changes the method which Active Admin calls

+  # config.pundit_default_policy = "MyDefaultPunditPolicy"
+
+  # If you wish to maintain a separate set of Pundit policies for admin

+  # within when looking for a resource's policy.

+  # This is necessary in order to prevent a redirect loop which happens
+  # because, by default, user gets redirected to Dashboard. If user
+  # doesn't have access to Dashboard, he'll end up in a redirect loop.
+  # Method provided here should be defined in application_controller.rb.

+  # == Current User
+  #
+  # Active Admin will associate actions with the current
+  # user performing them.

+  # This setting changes the method which Active Admin calls
+  # (within the application controller) to return the currently logged in user.
+  config.current_user_method = :current_admin_user
+
+  # == Logging Out
+  #
+  # Active Admin displays a logout link on each screen. These
+  # settings configure the location and method used for the link.
+  #
+  # This setting changes the path where the link points to. If it's
+  # a string, the strings is used as the path. If it's a Symbol, we
+  # will call the method to return the path.
+  #
+  # Default:
+  config.logout_link_path = :destroy_admin_user_session_path
+
+  # This setting changes the http method used when rendering the
+  # link. For example :get, :delete, :put, etc..
+  #
+  # Default:
+  # config.logout_link_method = :get
+
+  # == Root
+  #
+  # Set the action to call for the root path. You can set different
+  # roots for each namespace.
+  #
+  # Default:
+  # config.root_to = 'dashboard#index'
+
+  # == Admin Comments
+  #
+  # This allows your users to comment on any resource registered with Active Admin.

+  # You can completely disable comments:

+  # You can change the order for the comments and you can change the column

+  # https://guides.rubyonrails.org/i18n.html

+  # You can run `bin/rails runner 'puts I18n.t("date.formats")'` to see the

+  # == Setting a Favicon
+  #

+  #
+  # Add tags to all pages logged in users see:
+  #   config.meta_tags = { author: 'My Company' }
+
+  # By default, sign up/sign in/recover password pages are excluded
+  # from showing up in search engine results by adding a robots meta
+  # tag. You can reset the hash of meta tags included in logged out
+  # pages:
+  #   config.meta_tags_for_logged_out_pages = {}
+
+  # == Removing Breadcrumbs
+  #
+  # Breadcrumbs are enabled by default. You can customize them for individual
+  # resources or you can disable them globally from here.
+  #
+  # config.breadcrumb = false
+
+  # == Create Another Checkbox
+  #
+  # Create another checkbox is disabled by default. You can customize it for individual
+  # resources or you can enable them globally from here.
+  #
+  # config.create_another = true
+
+  # == Register Stylesheets & Javascripts
+  #
+  # We recommend using the built in Active Admin layout and loading
+  # up your own stylesheets / javascripts to customize the look
+  # and feel.
+  #
+  # To load a stylesheet:
+  #   config.register_stylesheet 'my_stylesheet.css'
+  #
+  # You can provide an options hash for more control,
+  # which is passed along to stylesheet_link_tag():
+  #   config.register_stylesheet 'my_print_stylesheet.css', media: :print
+  #
+  # To load a javascript file:
+  #   config.register_javascript 'my_javascript.js'
+
+  # == CSV options
+  #
+  # Set the CSV builder separator
+  # config.csv_options = { col_sep: ';' }
+  #
+  # Force the use of quotes
+  # config.csv_options = { force_quotes: true }
+
+  # == Menu System
+  #
+  # You can add a navigation menu to be used in your application, or configure a provided menu
+  #
+  # To change the default utility navigation to show a link to your website & a logout btn
+  #
+  #   config.namespace :admin do |admin|
+  #     admin.build_menu :utility_navigation do |menu|
+  #       menu.add label: "My Great Website", url: "http://www.mygreatwebsite.com", html_options: { target: :blank }
+  #       admin.add_logout_button_to_menu menu
+  #     end

+  #       menu.add label: "My Great Website", url: "http://www.mygreatwebsite.com", html_options: { target: "_blank" }
+  #     end
+  #   end
+
+  # == Download Links
+  #
+  # You can disable download links on resource listing pages,
+  # or customize the formats shown per namespace/globally
+  #
+  # To disable/customize for the :admin namespace:
+  #
+  #   config.namespace :admin do |admin|
+  #
+  #     # Disable the links entirely
+  #     admin.download_links = false
+  #
+  #     # Only show XML & PDF options
+  #     admin.download_links = [:xml, :pdf]
+  #
+  #     # Enable/disable the links based on block
+  #     #   (for example, with cancan)
+  #     admin.download_links = proc { can?(:view_download_links) }
+  #
+  #   end
+
+  # == Pagination
+  #
+  # Pagination is enabled by default for all resources.
+  # You can control the default per page count for all resources here.
+  #
+  # config.default_per_page = 30
+  #
