+# ol
+
+OpenLayers as ES2015 modules.
+
+**Note: This package is in beta and the API is subject to change before a final stable release.**
+
+## Usage
+
+Add the `ol` package as a dependency to your project.
+
+    npm install ol --save
+
+Import just what you need for your application:
+
+```js
+import Map from 'ol/map';
+import View from 'ol/view';
+import TileLayer from 'ol/layer/tile';
+import XYZ from 'ol/source/xyz';
+
+new Map({
+  target: 'map',
+  layers: [
+    new TileLayer({
+      source: new XYZ({
+        url: 'https://{a-c}.tile.openstreetmap.org/{z}/{x}/{y}.png'
+      })
+    })
+  ],
+  view: new View({
+    center: [0, 0],
+    zoom: 2
+  })
+});
+```
+
+See the following examples for more detail on bundling OpenLayers with your application:
+
+ * Using [Rollup & Uglify](https://gist.github.com/tschaub/8beb328ea72b36446fc2198d008287de)
+ * Using [Rollup & Closure Compiler](https://gist.github.com/tschaub/32a5692bedac5254da24fa3b12072f35)
+ * Using [Webpack & Uglify](https://gist.github.com/tschaub/79025aef325cd2837364400a105405b8)
+ * Using [Browserify & Uglify](https://gist.github.com/tschaub/4bfb209a8f809823f1495b2e4436018e)
+
+## Module Identifiers
+
+The module identifiers above (e.g. `ol/map`) are like the `ol.Map` names in the [API documentation](http://openlayers.org/en/latest/apidoc/) with `/` instead of `.` and all lowercase.  Each module only has a `default` export (there are no other named exports).
+
+Constructors are exported from dedicated modules.  For example, the `ol/layer/tile` module exports the `Tile` layer constructor.
+
+Utility functions are available as properties of the default export from utility modules.  For example, the `getCenter` function is a property of the default export from the `ol/extent` utility module.
+
+## Caveats
+
+ * Module identifiers and the structure of the exports are subject to change while this package is in beta.
+ * The WebGL renderer is not available in this package.
