+## lineSplit
+
+Split a LineString by another GeoJSON Feature.
+
+**Parameters**
+
+-   `line` **[Feature][1]&lt;[LineString][2]>** LineString Feature to split
+-   `splitter` **[Feature][1]&lt;any>** Feature used to split line
+
+**Examples**
+
+```javascript
+var line = turf.lineString([[120, -25], [145, -25]]);
+var splitter = turf.lineString([[130, -15], [130, -35]]);
+
+var split = turf.lineSplit(line, splitter);
+
+//addToMap
+var addToMap = [line, splitter]
+```
+
+Returns **[FeatureCollection][3]&lt;[LineString][2]>** Split LineStrings

+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/line-split
+```
+
+Or install the Turf module that includes it as a function:
+
+```sh
+$ npm install @turf/turf
+```
