+
+[Radio buttons](https://www.google.com/design/spec/components/selection-controls.html#selection-controls-radio-button) allow the user to select one option from a set. Use radio buttons for exclusive selection if you think that the user needs to see all available options side-by-side. Otherwise, consider a dropdown, which uses less space than displaying all options. They should always be used along with `RadioGroup`.
+
+<!-- example -->
+```jsx
+import { RadioGroup, RadioButton } from 'react-toolbox';
+
+const RadioTest = () => (
+  <RadioGroup ref='group' name='comic' value='vvendetta'>
+    <RadioButton label='The Walking Dead' value='thewalkingdead'/>
+    <RadioButton label='From Hell' value='fromhell' disabled/>
+    <RadioButton label='V for a Vendetta' value='vvendetta'/>
+    <RadioButton label='Watchmen' value='watchmen'/>
+  </RadioGroup>
+);
+```
+
+## Radio Group
+
+A radio selector is mean to get a value from a set of choices, that's why a radio group is needed. It can take some properties and actions that will be transferred to the children, but they also can behave independently.
+
+| Name              | Type          | Default         | Description|
+|:-----|:-----|:-----|:-----|
+| `className`   | `String`    |  `''`    | Set a class to give custom styles to the group.| 
+| `disabled`   | `Boolean`    |  `false`    | If true, the group will be displayed as disabled.| 
+| `name`    | `String`    |  | Name for the input element group. |
+| `onChange`    | `Function`    |   | Callback function that will be invoked when the value changes. |
+| `value`    | `Any`    |  | Default value selected in the radio group. |
+
+This component has state to keep the currently selected value and that's why it exposes to methods to work from the code with it:
+- `getValue` used to retrieve the currently selected value.
+- `setValue` used to set a new value.
+
+## Radio Button
+
+The inner component to compose radio selectors. They will be rendered as radio input elements of HTML transferring the given properties that concerns to them.
+
+| Name              | Type          | Default         | Description|
+|:-----|:-----|:-----|:-----|
+| `checked`   | `Boolean`    |  `false`    | If true, the input element will be selected by default. Transferred from the parent. | 
+| `className`   | `String`    |  `''`    | Set a class to give custom styles to the radio button.| 
+| `disabled`   | `Boolean`    |  `false`    | If true, the item will be displayed as disabled.| 
+| `name`    | `String`    |  | Name for the input element. |
+| `onBlur`    | `Function`    |   | Callback function that will be invoked when the input is blurred. |
+| `onChange`    | `Function`    |   | Callback function that will be invoked when the value changes. |
+| `onFocus`    | `Function`    |   | Callback function that will be invoked when the input is focused. |
+| `value`    | `Any`    |  | Value for the radio button. |
