+This is a basic basemap + deck.gl data animation utilizing [react-map-gl](https://visgl.github.io/react-map-gl/) and `PolygonLayer`.
+
+### Usage
+
+Copy the content of this folder to your project. 
+
+To see the base map, you need a [Mapbox access token](https://docs.mapbox.com/help/how-mapbox-works/access-tokens/). You can either set an environment variable:
+
+```bash
+export MapboxAccessToken=<mapbox_access_token>
+```
+
+Or set `MAPBOX_TOKEN` directly in `app.js`.
+
+Other options can be found at [using with Mapbox GL](https://deck.gl/docs/developer-guide/base-maps/using-with-mapbox).
+
+### Installation
+
+```bash
+# install dependencies within hubble.gl root
+yarn bootstrap
+# To install example go to the folder 
+cd examples/basic-basemap-mapbox-legacy
+# do this once per example
+yarn 
+# To run the example
+yarn start-local
+```
+
+### Data format
+Sample data is stored in [deck.gl Example Data](https://github.com/visgl/deck.gl-data/tree/master/examples). To use your own data, check out
+the [documentation of PolygonLayer](https://deck.gl/docs/api-reference/layers/polygon-layer).
+
+### How to add this feature to a hubble.gl example
+
+1. Define hubble.gl react hooks
+
+```jsx
+import React, {useRef} from 'react';
+import {useDeckAnimation, useHubbleGl} from '@hubble.gl/react';
+
+const initialViewState = {...};
+
+function Map() {
+  const deckRef = useRef(null);
+  const mapRef = useRef(null);
+  const deckAnimation = useDeckAnimation({
+    getLayers: a =>
+      a.applyLayerKeyframes([
+         // move deck layer definitions to here
+      ]),
+    layerKeyframes: ...
+    cameraKeyframe: ...
+  });
+
+  const {
+    deckProps, 
+    mapProps,          // optional, use for basemap
+    adapter,           // optional, use to modify animation at run time
+    cameraFrame,       // optional, use for camera animation
+    setCameraFrame     // optional, use for camera animation
+  } = useHubbleGl({
+      deckRef,
+      mapRef,          // optional, use for basemap
+      deckAnimation,
+      initialViewState // optional, use for camera animation
+  });
+
+  ...
+```
+
+2. Define animation and export settings
+
+```js
+const formatConfigs = {
+  // optional, override default quality settings
+};
+
+const resolution = {
+  width: 1280,
+  height: 720
+};
+
+const timecode = {
+  start: 0,
+  end: 5000,
+  framerate: 30
+};
+```
+
+3. Define an interleaved deck.gl `MapboxOverlay`
+
+```jsx
+import {forwardRef} from 'react';
+import Map, {useControl} from 'react-map-gl';
+import {MapboxOverlay} from '@deck.gl/mapbox';
+
+const DeckGLOverlay = forwardRef((props, ref) => {
+  // MapboxOverlay handles a variety of props differently than the Deck class.
+  // https://deck.gl/docs/api-reference/mapbox/mapbox-overlay#constructor
+  const deck = useControl(() => new MapboxOverlay({...props, interleaved: true}));
+  deck.setProps(props);
+  ref.current = deck._deck;
+  return null;
+});
+```
+
+4. Add to props of the `DeckGLOverlay ` and `Map` component
+
+```jsx
+  <Map
+    ref={mapRef}
+    {...cameraFrame}
+    style={{width: resolution.width, height: resolution.height}}
+    {/* add your props before spreading hubble props */}
+    {...mapProps}
+  >
+    <DeckGLOverlay 
+      ref={deckRef} 
+      {/* add your props before spreading hubble props */}
+      {...deckProps}
+    />
+  </Map>
+```
