 ### JSX
 
 After installing `react-rails`, restart your server. Now, `.js.jsx` files will be transformed in the asset pipeline.
 
-`react-rails` currently ships with two transformers, to convert jsx code -
-
-* `BabelTransformer` using [Babel](http://babeljs.io), which is the default transformer.
-* `JSXTransformer` using `JSXTransformer.js`

-You can use the deprecated `JSXTransformer` by setting it in an application config:

-```ruby
-  config.react.jsx_transformer_class = React::JSX::JSXTransformer

 #### BabelTransformer options
 
 You can use babel's [transformers](http://babeljs.io/docs/advanced/transformers/) and [custom plugins](http://babeljs.io/docs/advanced/plugins/),
 and pass [options](http://babeljs.io/docs/usage/options/) to the babel transpiler adding following configurations:

 ### Rendering & mounting
 
 `react-rails` includes a view helper (`react_component`) and an unobtrusive JavaScript driver (`react_ujs`)
 which work together to put React components on the page. You should require the UJS driver
  in your manifest after `react` (and after `turbolinks` if you use [Turbolinks](https://github.com/rails/turbolinks)).

 If Turbolinks is present components are mounted on the `page:change` event, and unmounted on `page:before-unload`.
  __Turbolinks >= 2.4.0__ is recommended because it exposes better events.
 
+In case of __Ajax calls__, the UJS mounting can be triggered manually by calling from javascript:
