+
+  # 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

+  # Default:

+  #
+  # config.favicon = 'favicon.ico'
+

+  #
+  # Add additional meta tags to the head element of active admin pages.
+  #
+  # 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

+
+  # == Register Stylesheets & Javascripts
+  #
+  # We recommend using the built in Active Admin layout and loading

+  # 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|

+  #       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

+  #     # 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.
+  # You can enabled or disable the inclusion
+  # of those filters by default here.
+  #
+  # config.include_default_association_filters = true

+
+  # ==> Configuration for :encryptable
+  # Allow you to use another encryption algorithm besides bcrypt (default). You can use

+  # REST_AUTH_SITE_KEY to pepper).
+  #
+  # Require the `devise-encryptable` gem when using anything other than bcrypt
+  # config.encryptor = :sha512
+
+  # ==> Scopes configuration
+  # Turn scoped views on. Before rendering "sessions/new", it will first check for

+  # are using only default views.
+  # config.scoped_views = false

+  # only the current scope. By default, Devise signs out all scopes.
+  # config.sign_out_all_scopes = true
+
+  # ==> Navigation configuration
+  # Lists the formats that should be treated as navigational. Formats like
+  # :html, should redirect to the sign in page when the user does not have
+  # access, but formats like :xml or :json, should return 401.
+  #

+  # up on your models and hooks.

+
+  # ==> Warden configuration
+  # If you want to use other strategies, that are not supported by Devise, or
+  # change the failure app, you can configure them inside the config.warden block.
+  #
+  # config.warden do |manager|
+  #   manager.intercept_401 = false
+  #   manager.default_strategies(scope: :user).unshift :some_external_strategy
+  # end
+
+  # ==> Mountable engine configurations
+  # When using Devise inside an engine, let's call it `MyEngine`, and this engine
+  # is mountable, there are some extra configurations to be taken into account.
+  # The following options are available, assuming the engine is mounted as:
+  #
+  #     mount MyEngine, at: '/my_engine'
+  #
+  # The router that invoked `devise_for`, in the example above, would be:
+  # config.router_name = :my_engine
+  #
+  # When using OmniAuth, Devise cannot automatically set OmniAuth path,
+  # so you need to do it manually. For the users scope, it would be:
+  # config.omniauth_path_prefix = '/my_engine/users/auth'
