-## Markdown in Detail
-
-The grape-swagger gem allows you to add an explanation in markdown in the detail field. Which would result in proper formatted markdown in Swagger UI.
-Grape-swagger uses adapters for several markdown formatters. It includes adapters for [kramdown](http://kramdown.rubyforge.org) (kramdown [syntax](http://kramdown.rubyforge.org/syntax.html)) and [redcarpet](https://github.com/vmg/redcarpet).
-The adapters are packed in the GrapeSwagger::Markdown modules. We do not include the markdown gems in our gemfile, so be sure to include or install the depended gems.
-
-To use it, add a new instance of the adapter to the markdown options of `add_swagger_documentation`, such as:
-```ruby
-add_swagger_documentation \
-  markdown: GrapeSwagger::Markdown::KramdownAdapter.new(options)
-```
-and write your route details in GFM, examples could be find in [details spec](blob/master/spec/swagger_v2/api_swagger_v2_detail_spec.rb)
-
-
-#### Kramdown
-If you want to use kramdown as markdown formatter, you need to add kramdown to your gemfile.
-
-```ruby
-gem 'kramdown'
-```
-
-Configure your api documentation route with:
-```ruby
-add_swagger_documentation \
-  markdown: GrapeSwagger::Markdown::KramdownAdapter.new(options)
-```
-
+## Markdown in Detail (deprecated)
 
-#### Redcarpet
-As alternative you can use [redcarpet](https://github.com/vmg/redcarpet) as formatter, you need to include redcarpet in your gemspec. If you also want to use [rouge](https://github.com/jneen/rouge) as syntax highlighter you also need to include it.
-
-```ruby
-gem 'redcarpet'
-gem 'rouge'
-```
-
-Configure your api documentation route with:
-
-```ruby
-add_swagger_documentation(
-  markdown: GrapeSwagger::Markdown::RedcarpetAdapter.new(render_options: { highlighter: :rouge })
-)
-```
-
-Alternatively you can disable rouge by adding `:none` as highlighter option. You can add redcarpet extensions and render options trough the `extenstions:` and `render_options:` parameters.
-
-
-#### Custom markdown formatter
-
-You can also add your custom adapter for your favourite markdown formatter, as long it responds to the method `markdown(text)` and it formats the given text.
-
-
-```ruby
-module API
-
-  class FancyAdapter
-   attr_reader :adapter
-
-   def initialize(options)
-    require 'superbmarkdownformatter'
-    @adapter = SuperbMarkdownFormatter.new options
-   end
-
-   def markdown(text)
-      @adapter.render_supreme(text)
-   end
-  end
-
-  add_swagger_documentation markdown: FancyAdapter.new(no_links: true)
-end
-```
