+
+Higher level content negotiation based on [negotiator](https://www.npmjs.com/package/negotiator).
+Extracted from [koa](https://www.npmjs.com/package/koa) for general use.
+
+In addition to negotiator, it allows:
+
+- Allows types as an array or arguments list, ie `(['text/html', 'application/json'])`
+  as well as `('text/html', 'application/json')`.
+- Allows type shorthands such as `json`.
+- Returns `false` when no types match
+- Treats non-existent headers as `*`
+
+## 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 accepts
+```
+
+## API
+
+<!-- eslint-disable no-unused-vars -->
+
+```js
+var accepts = require('accepts')
+```
+
+### accepts(req)
+
+Create a new `Accepts` object for the given `req`.
+
+#### .charset(charsets)
+
+Return the first accepted charset. If nothing in `charsets` is accepted,
+then `false` is returned.
+
+#### .charsets()
+
+Return the charsets that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .encoding(encodings)
+
+Return the first accepted encoding. If nothing in `encodings` is accepted,
+then `false` is returned.
+
+#### .encodings()
+
+Return the encodings that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .language(languages)
+
+Return the first accepted language. If nothing in `languages` is accepted,
+then `false` is returned.
+
+#### .languages()
+
+Return the languages that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .type(types)
+
+Return the first accepted type (and it is returned as the same text as what
+appears in the `types` array). If nothing in `types` is accepted, then `false`
+is returned.
+
+The `types` array can contain full MIME types or file extensions. Any value
+that is not a full MIME types is passed to `require('mime-types').lookup`.
+
+#### .types()
+
+Return the types that the request accepts, in the order of the client's
+preference (most preferred first).
+
+## Examples
+
+### Simple type negotiation
+
+This simple example shows how to use `accepts` to return a different typed
+respond body based on what the client wants to accept. The server lists it's
+preferences in order and will get back the best match between the client and
+server.
+
+```js
+var accepts = require('accepts')
+var http = require('http')
+
+function app (req, res) {
+  var accept = accepts(req)
+
+  // the order of this list is significant; should be server preferred order
+  switch (accept.type(['json', 'html'])) {
+    case 'json':
+      res.setHeader('Content-Type', 'application/json')
+      res.write('{"hello":"world!"}')
+      break
+    case 'html':
+      res.setHeader('Content-Type', 'text/html')
+      res.write('<b>hello, world!</b>')
+      break
+    default:
+      // the fallback is text/plain, so no need to specify it above
+      res.setHeader('Content-Type', 'text/plain')
+      res.write('hello, world!')
+      break
+  }
+
+  res.end()
+}
+
+http.createServer(app).listen(3000)
+```
+
+You can test this out with the cURL program:
+```sh
+curl -I -H'Accept: text/html' http://localhost:3000/
+```
