-### Server Rendering
-
-For performance and thread-safety reasons, a pool of JS VMs are spun up on application start, and the size of the pool and the timeout on requesting a VM from the pool are configurable.
-
-```ruby
-# config/environments/application.rb
-# These are the defaults if you dont specify any yourself
-MyApp::Application.configure do
-  config.react.max_renderers = 10
-  config.react.timeout = 20 #seconds
-  config.react.react_js = lambda {File.read(::Rails.application.assets.resolve('react.js'))}
-  config.react.component_filenames = ['components.js']
-  config.react.replay_console = false
-end
-```
-
-Other configuration options include:
-* `react_js`: where you want to grab the javascript library from
-* `component_filenames`: an array of filenames that will be requested from the asset pipeline and concatenated together
-* `replay_console`: additional debugging by replaying any captured console messages from server-rendering back on the client (note: they will lose their call stack, but it can help point you in right direction)

 ## CoffeeScript
 
 It is possible to use JSX with CoffeeScript. The caveat is that you will still need to include the docblock. Since CoffeeScript doesn't allow `/* */` style comments, we need to do something a little different. We also need to embed JSX inside backticks so CoffeeScript ignores the syntax it doesn't understand. Here's an example:

-### Changing react.js and JSXTransformer.js versions
-
-In some cases you may want to have your `react.js` and `JSXTransformer.js` files come from a different release than the one, that is specified in the `react-rails.gemspec`. To achieve that, you have to manually replace them in your app.
-
-#### Instructions
-
-Just put another version of `react.js` or `JSXTransformer.js` under `/vendor/assets/react` directory.
-If you need different versions of `react.js` for production and development, then use a subdirectory named
-after `config.react.variant`, e.g. you set `config.react.variant = :development` so for this environment
-`react.js` is expected to be in `/vendor/assets/react/development`
-
-#### Things to remember
-
-If you replace `JSXTransformer.js` in production environment, you have to restart your rails instance,
-because the jsx compiler context is cached.
-
-Name of the `JSXTransformer.js` file *is case-sensitive*.
