 ## Quick Overview
 
-Reactrb components are ruby classes that inherit from `React::Component::Base` or include `React::Component`.
+A component is a plain ruby class with a `#render` method defined.
 
-`React::Component` provides a complete DSL to generate html and event handlers, and has full set of class macros to define states, parameters, and lifecycle callbacks.
+```ruby
+class HelloMessage
+  def render
+    React.create_element("div") { "Hello World!" }
+  end
+end
 
-Each react component class has a render method that generates the markup for that component.
+puts React.render_to_static_markup(React.create_element(HelloMessage))
 
-Each react component class defines a new tag-method in the DSL that works just like built-in html tags, so react components can render other react components.
+# => '<div>Hello World!</div>'
+```
 
-As events occur, components update their state, which causes them to rerender, and perhaps pass new parameters to lower level components, thus causing them to rerender.  
+### React::Component
 
-Under the hood the actual work is effeciently done by the [React.js](http://facebook.github.io/reactrb/) engine.
+You can simply include `React::Component` to get the power of a complete DSL to generate html markup, event handlers and it also provides a full set of class macros to define states, parameters, and lifecycle callbacks.
+
+As events occur, components update their state, which causes them to rerender, and perhaps pass new parameters to lower level components, thus causing them to rerender.
+
+```ruby
+class HelloWorld < React::Component::Base
+  param :time, type: Time
+  render do
+    p do
+      span { "Hello, " }
+      input(type: :text, placeholder: "Your Name Here")
+      span { "! It is #{params.time}"}
+    end
+  end
+end
+
+every(1) do
+  Element["#example"].render do
+    HelloWorld(time: Time.now)
+  end
+end
+```

+Reactrb components are *isomorphic* (or *univeral*) meaning they can run on the server as well as the client.

+Reactrb integrates well with Rails, Sinatra, and simple static sites, and can be added to existing web pages very easily.
 
-Reactrb components are *isomorphic* meaning they can run on the server as well as the client.  This means that the initial expansion of the component tree to markup is done server side, just like ERB, or HAML templates.   Then the same code runs on the client and will respond to any events.   
+Under the hood the actual work is effeciently done by the [React.js](http://facebook.github.io/reactrb/) engine.

 1. Replace `reactive-ruby` with `reactrb` both in **Gemfile** and any `require`s in your code.
 2. To include the React.js source, the suggested way is to add `require 'react/react-source'` before `require 'reactrb'`. This will use the copy of React.js source from `react-rails` gem.
