+# leaflet-control-react
+
+Leaflet Control that renders a react component onto the map.
+
+## Usage
+
+The control is provided as a [UMD](https://github.com/umdjs/umd) module.
+
+Basic usage:
+
+```js
+var label = 'Hello Leaflet!';
+
+function getElement () {
+  return React.DOM.div({ className: 'leaflet-control-with-react' }, label);
+}
+
+var reactControl = L.control.react({
+  position: 'bottomleft',
+  getElement: getElement
+}).addTo(map);
+
+/* Change some props, and re-render: */
+label = 'Hello React!';
+reactControl.render();
+```
+
+The `getElement` function gets the leaflet `map` as its argument.
+
+The react components are rendered into a `div` with `leaflet-control-react`, and the default `leaflet-control` classes.
+
+## Options
+
+`getElement` - A function with a single `L.Map` argument. The return value is rendered as:
+```
+ReactDOM.render(this.options.getElement(this._map), this._container);
+```
+when the control is added to the map, and anytime the `.render()` function is called.
+
+`position` - Inherited from `L.Control`
+
+## Events
+
+You should be able to use the [react event system](https://facebook.github.io/react/docs/events.html), since it's just a thin wrapper around your react component.
