+  # Define your dashboard sections here. Each block will be

+  # Here is an example of a simple dashboard section

+  #   section "Recent Posts" do

+  #
+  #   section "Recent Posts" do

+
+  # == Section Ordering
+  # The dashboard sections are ordered by a given priority from top left to
+  # bottom right. The default priority is 10. By giving a section numerically lower
+  # priority it will be sorted higher. For example:
+  #
+  #   section "Recent Posts", :priority => 10
+  #   section "Recent User", :priority => 1
+  #
+  # Will render the "Recent Users" then the "Recent Posts" sections on the dashboard.
+
+  # == Conditionally Display
+  # Provide a method name or Proc object to conditionally render a section at run time.
+  #
+  # section "Membership Summary", :if => :memberships_enabled?
+  # section "Membership Summary", :if => Proc.new { current_admin_user.account.memberships.any? }

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

+  #
+  # Note: Recommended image height is 21px to properly fit in the header
+  #
+  # config.site_title_image = "/images/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

+  #
+  #   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
+  # within the controller.
+  config.authentication_method = :authenticate_admin_user!
+
+
+  # == Current User
+  #
+  # Active Admin will associate actions with the current
+  # user performing them.
+  #
+  # This setting changes the method which Active Admin calls
+  # 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
+
+
+  # == Admin Comments
+  #
+  # Admin comments allow you to add comments to any model for admin use.
+  # Admin comments are enabled by default.
+  #
+  # Default:
+  # config.allow_comments = true
+  #
+  # You can turn them on and off for any given namespace by using a
+  # namespace config block.
+  #
+  # Eg:
+  #   config.namespace :without_comments do |without_comments|
+  #     without_comments.allow_comments = false
+  #   end

+
+  # == Controller Filters
+  #
+  # You can add before, after and around filters to all of your
+  # Active Admin resources from here.
+  #
+  # config.before_filter :do_something_awesome
+
+
+  # == 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'
