+
+# geojson-rewind
+
+The [GeoJSON](https://tools.ietf.org/html/rfc7946) specification is [picky about winding order](https://tools.ietf.org/html/rfc7946#section-3.1.6).
+
+This helps you generate compliant Polygon and MultiPolygon geometries. Furthermore it lets you use [Canvas](http://www.bit-101.com/blog/?p=3702) and other drawing libraries's default behavior to color the interior rings of Polygon and MultiPolygon features.
+
+## Usage
+
+As NPM module:
+
+    npm install --save @mapbox/geojson-rewind
+
+As a console utility:
+
+    # install
+    npm install -g @mapbox/geojson-rewind
+    # use
+    geojson-rewind foo.geojson
+
+As a browser library: [geojson-rewind.js](https://bundle.run/geojson-rewind)
+
+## API
+
+`rewind(geojson, clockwise)`
+
+Given a GeoJSON FeatureCollection, Feature, or Geometry, return a version
+with inner and outer rings of different winding orders.
+
+If `clockwise` is `true`, the outer ring is clockwise, otherwise
+it is counterclockwise.
