   * Mongoid
 
-## Installation
-After you bundled the gem, mount RailsAdmin gem in `config/routes.rb`:
 
-```ruby
-mount RailsAdmin::Engine => '/admin', :as => 'rails_admin' # Change '/admin' to any namespace you like.
-```
 
-Start a server `rails s` and administer your data at [/admin](http://localhost:3000/admin).
+## Installation
+
+1. Bundle the gem
+2. Run `rails g rails_admin:install`
+3. Provide a namespace for the routes when asked
+4. Start a server `rails s` and administer your data at [/admin](http://localhost:3000/admin). (if you chose default namespace: /admin)
 
 ## Configuration
 ### Global
 In `config/initializers/rails_admin`:
 
-```ruby
-RailsAdmin.config do |config|
-  config.main_app_name = ["Cool app", "BackOffice"]
-  # ...
-end
-```
-
 [Details](https://github.com/sferik/rails_admin/wiki/Base-configuration)
 
 To begin with, you may be interested in setting up [Devise](https://github.com/sferik/rails_admin/wiki/Devise), [Cancan](https://github.com/sferik/rails_admin/wiki/Cancan) or [Papertrail](https://github.com/sferik/rails_admin/wiki/Papertrail)!

-  ################  Model configuration  ################
-
-  # Each model configuration can alternatively:
-  #   - stay here in a `config.model 'ModelName' do ... end` block
-  #   - go in the model definition file in a `rails_admin do ... end` block
-
-  # This is your choice to make:
-  #   - This initializer is loaded once at startup (modifications will show up when restarting the application) but all RailsAdmin configuration would stay in one place.
-  #   - Models are reloaded at each request in development mode (when modified), which may smooth your RailsAdmin development workflow.
-
-
-  # Now you probably need to tour the wiki a bit: https://github.com/sferik/rails_admin/wiki
-  # Anyway, here is how RailsAdmin saw your application's models when you ran the initializer:
-
-<% RailsAdmin::AbstractModel.all.map do |abstract_model| -%>
-
-
-  ###  <%= abstract_model.model.model_name %>  ###
-
-  # config.model '<%= abstract_model.model.model_name %>' do
-
-  #   # You can copy this to a 'rails_admin do ... end' block inside your <%= abstract_model.model.model_name.to_s.underscore %>.rb model definition
-
-  #   # Found associations:
-
-<%= abstract_model.config.export.fields.select{|f| f.association?}.map do |field|
-%{  #     configure #{field.name.inspect}, #{field.type.inspect}#{"         # Hidden" unless field.visible?} }
-end.join("\n") %>
-
-  #   # Found columns:
-
-<%= abstract_model.config.export.fields.select{|f| !f.association?}.map do |field|
-%{  #     configure #{field.name.inspect}, #{field.type.inspect}#{"         # Hidden" unless field.visible?} }
-end.join("\n") %>
-
-  #   # Cross-section configuration:
-
-  #     # object_label_method :name     # Name of the method called for pretty printing an *instance* of ModelName
-  #     # label 'My model'              # Name of ModelName (smartly defaults to ActiveRecord's I18n API)
-  #     # label_plural 'My models'      # Same, plural
-  #     # weight 0                      # Navigation priority. Bigger is higher.
-  #     # parent OtherModel             # Set parent model for navigation. MyModel will be nested below. OtherModel will be on first position of the dropdown
-  #     # navigation_label              # Sets dropdown entry's name in navigation. Only for parents!
-
-  #   # Section specific configuration:
-
-  #     list do
-  #       # filters [:id, :name]  # Array of field names which filters should be shown by default in the table header
-  #       # items_per_page 100    # Override default_items_per_page
-  #       # sort_by :id           # Sort column (default is primary key)
-  #       # sort_reverse true     # Sort direction (default is true for primary key, last created first)
-  #     end
-  #     show do; end
-  #     edit do; end
-  #     export do; end
-  #     # also see the create, update, modal and nested sections, which override edit in specific cases (resp. when creating, updating, modifying from another model in a popup modal or modifying from another model nested form)
-  #     # you can override a cross-section field configuration in any section with the same syntax `configure :field_name do ... end`
-  #     # using `field` instead of `configure` will exclude all other fields and force the ordering
