+# space-separated-tokens [![Build Status][build-badge]][build-page] [![Coverage Status][coverage-badge]][coverage-page]
+
+Parse and stringify space-separated tokens according to the [spec][].
+
+## Installation
+
+[npm][]:
+
+```bash
+npm install space-separated-tokens
+```
+
+**space-separated-tokens** is also available as an AMD, CommonJS, and
+globals module, [uncompressed and compressed][releases].
+
+## Usage
+
+Dependencies:
+
+```javascript
+var spaceSeparated = require('space-separated-tokens');
+```
+
+Parsing:
+
+```javascript
+var values = spaceSeparated.parse(' foo\tbar\nbaz  ');
+```
+
+Yields:
+
+```js
+[ 'foo', 'bar', 'baz' ]
+```
+
+Compiling:
+
+```javascript
+var value = spaceSeparated.stringify(values);
+```
+
+Yields:
+
+```js
+'foo bar baz'
+```
+
+## API
+
+### `spaceSeparated.parse(value)`
+
+Parse space-separated tokens to an array of strings, according to the [spec][].
+
+*   `value` (`string`) — space-separated tokens.
+
+**Returns**: `Array.<string>` — List of tokens.
+
+### `spaceSeparated.stringify(values)`
+
+Compile an array of strings to space-separated tokens.
+Note that it’s not possible to specify empty or white-space only values.
+
+*   `values` (`Array.<string>`) — List of tokens.
+
+**Returns**: `string` — Space-separated tokens.
