+
+An HTTP content negotiator for Node.js
+
+## Installation
+
+```sh
+$ npm install negotiator
+```
+
+## API
+
+```js
+var Negotiator = require('negotiator')
+```
+
+### Accept Negotiation
+
+```js
+availableMediaTypes = ['text/html', 'text/plain', 'application/json']
+
+// The negotiator constructor receives a request object
+negotiator = new Negotiator(request)
+
+// Let's say Accept header is 'text/html, application/*;q=0.2, image/jpeg;q=0.8'
+
+negotiator.mediaTypes()
+// -> ['text/html', 'image/jpeg', 'application/*']
+
+negotiator.mediaTypes(availableMediaTypes)
+// -> ['text/html', 'application/json']
+
+negotiator.mediaType(availableMediaTypes)
+// -> 'text/html'
+```
+
+You can check a working example at `examples/accept.js`.
+
+#### Methods
+
+##### mediaType()
+
+Returns the most preferred media type from the client.
+
+##### mediaType(availableMediaType)
+
+Returns the most preferred media type from a list of available media types.
+
+##### mediaTypes()
+
+Returns an array of preferred media types ordered by the client preference.
+
+##### mediaTypes(availableMediaTypes)
+
+Returns an array of preferred media types ordered by priority from a list of
+available media types.
+
+### Accept-Language Negotiation
+
+```js
+negotiator = new Negotiator(request)
+
+availableLanguages = ['en', 'es', 'fr']
+
+// Let's say Accept-Language header is 'en;q=0.8, es, pt'
+
+negotiator.languages()
+// -> ['es', 'pt', 'en']
+
+negotiator.languages(availableLanguages)
+// -> ['es', 'en']
+
+language = negotiator.language(availableLanguages)
+// -> 'es'
+```
+
+You can check a working example at `examples/language.js`.
+
+#### Methods
+
+##### language()
+
+Returns the most preferred language from the client.
+
+##### language(availableLanguages)
+
+Returns the most preferred language from a list of available languages.
+
+##### languages()
+
+Returns an array of preferred languages ordered by the client preference.
+
+##### languages(availableLanguages)
+
+Returns an array of preferred languages ordered by priority from a list of
+available languages.
+
+### Accept-Charset Negotiation
+
+```js
+availableCharsets = ['utf-8', 'iso-8859-1', 'iso-8859-5']
+
+negotiator = new Negotiator(request)
+
+// Let's say Accept-Charset header is 'utf-8, iso-8859-1;q=0.8, utf-7;q=0.2'
+
+negotiator.charsets()
+// -> ['utf-8', 'iso-8859-1', 'utf-7']
+
+negotiator.charsets(availableCharsets)
+// -> ['utf-8', 'iso-8859-1']
+
+negotiator.charset(availableCharsets)
+// -> 'utf-8'
+```
+
+You can check a working example at `examples/charset.js`.
+
+#### Methods
+
+##### charset()
+
+Returns the most preferred charset from the client.
+
+##### charset(availableCharsets)
+
+Returns the most preferred charset from a list of available charsets.
+
+##### charsets()
+
+Returns an array of preferred charsets ordered by the client preference.
+
+##### charsets(availableCharsets)
+
+Returns an array of preferred charsets ordered by priority from a list of
+available charsets.
+
+### Accept-Encoding Negotiation
+
+```js
+availableEncodings = ['identity', 'gzip']
+
+negotiator = new Negotiator(request)
+
+// Let's say Accept-Encoding header is 'gzip, compress;q=0.2, identity;q=0.5'
+
+negotiator.encodings()
+// -> ['gzip', 'identity', 'compress']
+
+negotiator.encodings(availableEncodings)
+// -> ['gzip', 'identity']
+
+negotiator.encoding(availableEncodings)
+// -> 'gzip'
+```
+
+You can check a working example at `examples/encoding.js`.
+
+#### Methods
+
+##### encoding()
+
+Returns the most preferred encoding from the client.
+
+##### encoding(availableEncodings)
+
+Returns the most preferred encoding from a list of available encodings.
+
+##### encodings()
+
+Returns an array of preferred encodings ordered by the client preference.
+
+##### encodings(availableEncodings)
+
+Returns an array of preferred encodings ordered by priority from a list of
+available encodings.
