+## tesselate
+
+Tesselates a [Feature&lt;Polygon>][1] into a [FeatureCollection&lt;Polygon>][2] of triangles
+using [earcut][3].
+
+**Parameters**
+
+-   `poly` **[Feature][4]&lt;[Polygon][5]>** the polygon to tesselate
+
+**Examples**
+
+```javascript
+var poly = turf.polygon([[[11, 0], [22, 4], [31, 0], [31, 11], [21, 15], [11, 11], [11, 0]]]);
+var triangles = turf.tesselate(poly);
+
+//addToMap
+var addToMap = [poly, triangles]
+```
+
+Returns **[FeatureCollection][6]&lt;[Polygon][5]>** a geometrycollection feature
+
+[1]: Feature<Polygon>
+
+[2]: FeatureCollection<Polygon>

+This module is part of the [Turfjs project](http://turfjs.org/), an open source
+module collection dedicated to geographic algorithms. It is maintained in the
+[Turfjs/turf](https://github.com/Turfjs/turf) repository, where you can create
+PRs and issues.
+
+### Installation
+
+Install this module individually:
+
+```sh
+$ npm install @turf/tesselate
+```
+
+Or install the Turf module that includes it as a function:
+
+```sh
+$ npm install @turf/turf
+```
