 - `separator` [optional]: a non-empty `string` that controls what the key separator is in the generated map. Defaults to `~`.
 - `space` [optional]: a `number` used to insert white space into the output JSON string for readability purposes, as per the `JSON.stringify` [documentation](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify#Parameters).
 
+### `order`
+
+To duplicate a JS object but containing a particular property order:
+```js
+const orderedObj = orderedJson.order(srcObj, map, 2);
+```
+
+#### Parameters
+- `srcObj`: an object with the properties in any order
+- `map` [optional]: the property map generated by `parse` above. If the map is unset, the response is a standard `JSON.stringify`. 
+- `separator` [optional]: a non-empty `string` that controls what the key separator is in the generated map. Defaults to `~`.

 ## Example
 
 An object with a particular property order:
