-### Enabling in a Rails-API Project
-
-The grape-swagger-rails gem uses the Rails asset pipeline for its Javascript and CSS. Enable the asset pipeline with [rails-api](https://github.com/rails-api/rails-api).
-
-Add sprockets to `config/application.rb`.
-
-```ruby
-require 'sprockets/railtie'
-```
-
-Include JavaScript in `app/assets/javascripts/application.js`.
-
-```javascript
-//
-//= require_tree .
-```
-
-Include CSS stylesheets in `app/assets/stylesheets/application.css`.
-
-```css
-/*
-*= require_tree .
-*/
-```
-
-### Enabling in Rails 6 (Sprokets 5)
-
-Rails 6 top-level targets are determined via `./app/assets/config/manifest.js`. Specify `grape-swagger-rails` asset files as follows.
-
-```javascript
-//= link grape_swagger_rails/application.css
-//= link grape_swagger_rails/application.js
-```
-
-See [Upgrading Sprokets](https://github.com/rails/sprockets/blob/master/UPGRADING.md#manifestjs) for more information.
