 ## Example Usage
 
-The library has one method, `parse`, which takes an array of objects with geometry data as the first parameter, an object consisting of settings for the second parameter, and an optional callback function as the third parameter. If a callback is not specified, the `parse` function returns the GeoJSON output.
+The library has one method, `parse`, which takes an array of objects (or a single object) with geometry data as the first parameter, an object consisting of settings for the second parameter, and an optional callback function as the third parameter.

 ```javascript
