+This is a minimal standalone version of the TerrainLayer example
+on [deck.gl](http://deck.gl) website.
+
+### Usage
+
+Copy the content of this folder to your project. 
+
+To load the terrain tiles, 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`.
+
+
+```bash
+# install dependencies
+npm install
+# or
+yarn
+# bundle and serve the app with webpack
+npm start
+```
+
+### Data format
+Mapbox's [terrain API](https://docs.mapbox.com/help/troubleshooting/access-elevation-data/#mapbox-terrain-rgb) encodes elevation data in raster tiles. To use other data sources, check out
+the [documentation of TerrainLayer](../../../docs/layers/terrain-layer.md).
