+
+If you're using React components in a larger non-React application or transitioning your code to React, you may need to keep references to components. `React.renderComponent` returns a reference to the mounted component:
+
+```js
+/** @jsx React.DOM */
+
+var myComponent = React.renderComponent(<MyComponent />, myContainer);
+```
+
+If you pass a variable to 'React.renderComponent`, it's not guaranteed that the component passed in will be the one that's mounted. In cases where you construct a component before mounting it, be sure to reassign your variable:
+
+```js
+/** @jsx React.DOM */
+
+var myComponent = <MyComponent />;
+
+// Some code here...
+
+myComponent = React.renderComponent(myComponent, myContainer);
+```
+
+> Note:
+>
+> This should only ever be used at the top level. Inside components, let your `props` and `state` handle communication with child components, and only reference components via `ref`s.
