 ## Rails and ActionView integration
 
-Require `tilt/pdf/rails` if you want to set up and register `tilt-pdf` as an
-ActionView template handler. You can do it in an initializer, or straight from
-the Gemfile:
-
-```ruby
-gem 'tilt-pdf', require: 'tilt/pdf/rails'
-```

-Put your three template files *together* in the relevant `app/views/foo` view
-directory, or use absolute paths using application/engine root. Work is in
-progress to enable better integration with Rails file layout.
