[Docs] Tip on integration with other libraries

Chose this title because it's more eye-catchy than "third-party integration".

 You can't access the children of your component through `this.props.children`. `this.props.children` designates the children being **passed onto you** by the owner:

+You don't have to go full React. The component [lifecycle events](/react/docs/component-specs.html#lifecycle-methods), especially `componentDidMount` and `componentDidUpdate`, are good places to put your other libraries' logic.
+
+```js
+var App = React.createClass({
+  getInitialState: function() {
+    return {myModel: new myBackboneModel({items: [1, 2, 3]})};
+  },
+
+  componentDidMount: function() {
+    $(this.refs.placeholder.getDOMNode()).append($('<span />'));
+  },
+
+  componentWillUnmount: function() {
+    // Clean up work here.
+  },
+
+  shouldComponentUpdate: function() {
+    // Let's just never update this component again.
+    return false;
+  },
+
+  render: function() {
+    return <div ref="placeholder"/>;
+  }
+});
+
+React.render(<App />, mountNode);
+```
+
+You can attach your own [event listeners](/react/tips/dom-event-listeners.html) and even [event streams](https://baconjs.github.io) this way.
