 ## tesselate
 
-Tesselates a [Feature\<Polygon>][1] into a [FeatureCollection\<Polygon>][2] of triangles
-using [earcut][3].
+Tesselates a polygon or multipolygon into a collection of triangle polygons
+using [earcut][1].
 
 ### Parameters
 
-*   `poly` **[Feature][4]<[Polygon][5]>** the polygon to tesselate
+*   `poly` **[Feature][2]<([Polygon][3] | [MultiPolygon][4])>** 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);
+const poly = turf.polygon([[[11, 0], [22, 4], [31, 0], [31, 11], [21, 15], [11, 11], [11, 0]]]);
+const triangles = turf.tesselate(poly);
 
 //addToMap
-var addToMap = [poly, triangles]
+const addToMap = [poly, triangles]
 ```
 
-Returns **[FeatureCollection][6]<[Polygon][5]>** a geometrycollection feature
+Returns **[FeatureCollection][5]<[Polygon][3]>** collection of polygon tesselations
