+Range header field parser.
+
+## Installation
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install range-parser
+```
+
+## API
+
+<!-- eslint-disable no-unused-vars -->
+
+```js
+var parseRange = require('range-parser')
+```
+
+### parseRange(size, header, options)
+
+Parse the given `header` string where `size` is the size of the selected
+representation that is to be partitioned into subranges. An array of subranges
+will be returned or negative numbers indicating an error parsing.
+
+  * `-2` signals a malformed header string
+  * `-1` signals an unsatisfiable range
+
+<!-- eslint-disable no-undef -->
+
+```js
+// parse header from request
+var subranges = parseRange(size, req.headers.range)
+
+// the type of the subranges
+if (subranges.type === 'bytes') {
+  // the ranges
+  subranges.forEach(function (r) {
+    // do something with r.start and r.end
+  })
+}
+```
+
+#### Options
+
+These properties are accepted in the options object.
+
+##### combine
+
+Specifies if overlapping & adjacent subranges should be combined, defaults to
+`false`. When `true`, ranges will be combined and returned as if they were
+specified that way in the header.
+
+<!-- eslint-disable no-undef -->
+
+```js
+parseRange(100, 'bytes=50-55,0-10,5-10,56-60', { combine: true })
+// => [
+//      { start: 0,  end: 10 },
+//      { start: 50, end: 60 }
+//    ]
+```
