+  config.site_title = "DLUHC CORE"
+
+  # Set the link url for the title. For example, to take

+  # Note: Aim for an image that's 21px high so it fits in the header.
+  #
+  # config.site_title_image = "logo.png"
+
+  # == 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

+  #
+  # This will ONLY change the title for the admin section. Other

+
+  # == 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 path where the link points to. If it's

+  #   config.meta_tags_for_logged_out_pages = {}

+  # 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
+  #   end
+  #
+  # If you wanted to add a static menu item to the default menu provided:
+  #
+  #   config.namespace :admin do |admin|
+  #     admin.build_menu :default do |menu|
+  #       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
+  #
+  # You can control the max per page count too.
+  #
+  # config.max_per_page = 10_000
+
+  # == Filters
+  #
+  # By default the index screen includes a "Filters" sidebar on the right
+  # hand side with a filter for each attribute of the registered model.
+  # You can enable or disable them for all resources here.
+  #
+  # config.filters = true
+  #
+  # By default the filters include associations in a select, which means
+  # that every record will be loaded for each association (up

+  # of those filters by default here.

+  #
+  # You can add your own content to the site head like analytics. Make sure
+  # you only pass content you trust.
+  #
+  # config.head = ''.html_safe
+
+  # == Footer
+  #
+  # By default, the footer shows the current Active Admin version. You can
+  # override the content of the footer here.
+  #
+  # config.footer = 'my custom footer text'
+
+  # == Sorting
+  #
+  # By default ActiveAdmin::OrderClause is used for sorting logic
+  # You can inherit it with own class and inject it for all resources
+  #
+  # config.order_clause = MyOrderClause
+
+  # == Webpacker
+  #
+  # By default, Active Admin uses Sprocket's asset pipeline.
+  # You can switch to using Webpacker here.
