+### Managing menu state
+Managing menu state works thru the exposed `menuActions`. To access `menuActions`, you need to use context. (there is an [awesome article](https://www.tildedave.com/2014/11/15/introduction-to-contexts-in-react-js.html) for that).
 
-Clicking on any menu item should cause closing menu. It can be done by using `menuActions` which are passed thru props to `menu` component. Example looks like this:
+`menuActions` consists of following method(s):
+- `close` (Void) - Close menu
+- `toggle` (Void) - Toggle menu (close / open)
+- `open` (Void) - Open menu
 
+Usage example:
 ```javascript
-var Menu = React.createClass({
-  about: function() {
-    this.props.menuActions.close();
-    this.props.navigator.push({...});
-  },
+class Button extends Component {
+  handlePress(e) {
+    this.context.menuActions.toggle();
+    if (this.props.onPress) {
+      this.props.onPress(e);
+    }
+  }
 
-  render: function() {
+  render() {
     return (
-      <View>
-        <Text>Menu</Text>
-        <Text onPress={this.about}>About</Text>
-      </View>
+      <TouchableOpacity
+        onPress={this.handlePress.bind(this)}>
+        <Text style={this.props.style}>{this.props.children}</Text>
+      </TouchableOpacity>
     );
   }
-});
-```
+}
 
-`menuActions` consists of following method(s):
-- `close` (Void) - Close menu
-- `toggle` (Void) - Toggle menu (close / open)
-- `open` (Void) - Open menu
+/**
+ * This part is very important. Without it you wouldn't be able to access `menuActions`
+ * @type {Object}
+ */
+Button.contextTypes = {
+  menuActions: React.PropTypes.object.isRequired
+};
+```
 
 ### Component props
