-
-## 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 cors
-```
-
-## Usage
-
-### Simple Usage (Enable *All* CORS Requests)
-
-```javascript
-var express = require('express')
-var cors = require('cors')
-var app = express()
-
-app.use(cors())
-
-app.get('/products/:id', function (req, res, next) {
-  res.json({msg: 'This is CORS-enabled for all origins!'})
-})
-
-app.listen(80, function () {
-  console.log('CORS-enabled web server listening on port 80')
-})
-```
-
-### Enable CORS for a Single Route
-
-```javascript
-var express = require('express')
-var cors = require('cors')
-var app = express()
-
-app.get('/products/:id', cors(), function (req, res, next) {
-  res.json({msg: 'This is CORS-enabled for a Single Route'})
-})
-
-app.listen(80, function () {
-  console.log('CORS-enabled web server listening on port 80')
-})
-```
-
-### Configuring CORS
-
-```javascript
-var express = require('express')
-var cors = require('cors')
-var app = express()
-
-var corsOptions = {
-  origin: 'http://example.com',
-  optionsSuccessStatus: 200 // some legacy browsers (IE11, various SmartTVs) choke on 204
-}
-
-app.get('/products/:id', cors(corsOptions), function (req, res, next) {
-  res.json({msg: 'This is CORS-enabled for only example.com.'})
-})
-
-app.listen(80, function () {
-  console.log('CORS-enabled web server listening on port 80')
-})
-```
-
-### Configuring CORS w/ Dynamic Origin
-
-```javascript
-var express = require('express')
-var cors = require('cors')
-var app = express()
-
-var whitelist = ['http://example1.com', 'http://example2.com']
-var corsOptions = {
-  origin: function (origin, callback) {
-    if (whitelist.indexOf(origin) !== -1) {
-      callback(null, true)
-    } else {
-      callback(new Error('Not allowed by CORS'))
-    }
-  }
-}
-
-app.get('/products/:id', cors(corsOptions), function (req, res, next) {
-  res.json({msg: 'This is CORS-enabled for a whitelisted domain.'})
-})
-
-app.listen(80, function () {
-  console.log('CORS-enabled web server listening on port 80')
-})
-```
-
-If you do not want to block REST tools or server-to-server requests,
-add a `!origin` check in the origin function like so:
-
-```javascript
-var corsOptions = {
-  origin: function (origin, callback) {
-    if (whitelist.indexOf(origin) !== -1 || !origin) {
-      callback(null, true)
-    } else {
-      callback(new Error('Not allowed by CORS'))
-    }
-  }
-}
-```
-
-### Enabling CORS Pre-Flight
-
-Certain CORS requests are considered 'complex' and require an initial
-`OPTIONS` request (called the "pre-flight request"). An example of a
-'complex' CORS request is one that uses an HTTP verb other than
-GET/HEAD/POST (such as DELETE) or that uses custom headers. To enable
-pre-flighting, you must add a new OPTIONS handler for the route you want
-to support:
-
-```javascript
-var express = require('express')
-var cors = require('cors')
-var app = express()
-
-app.options('/products/:id', cors()) // enable pre-flight request for DELETE request
-app.del('/products/:id', cors(), function (req, res, next) {
-  res.json({msg: 'This is CORS-enabled for all origins!'})
-})
-
-app.listen(80, function () {
-  console.log('CORS-enabled web server listening on port 80')
-})
-```
-
-You can also enable pre-flight across-the-board like so:
-
-```javascript
-app.options('*', cors()) // include before other routes
-```
-
-### Configuring CORS Asynchronously
-
-```javascript
-var express = require('express')
-var cors = require('cors')
-var app = express()
-
-var whitelist = ['http://example1.com', 'http://example2.com']
-var corsOptionsDelegate = function (req, callback) {
-  var corsOptions;
-  if (whitelist.indexOf(req.header('Origin')) !== -1) {
-    corsOptions = { origin: true } // reflect (enable) the requested origin in the CORS response
-  } else {
-    corsOptions = { origin: false } // disable CORS for this request
-  }
-  callback(null, corsOptions) // callback expects two parameters: error and options
-}
-
-app.get('/products/:id', cors(corsOptionsDelegate), function (req, res, next) {
-  res.json({msg: 'This is CORS-enabled for a whitelisted domain.'})
-})
-
-app.listen(80, function () {
-  console.log('CORS-enabled web server listening on port 80')
-})
-```
-
-## Configuration Options
-
-* `origin`: Configures the **Access-Control-Allow-Origin** CORS header. Possible values:
-  - `Boolean` - set `origin` to `true` to reflect the [request origin](http://tools.ietf.org/html/draft-abarth-origin-09), as defined by `req.header('Origin')`, or set it to `false` to disable CORS.
-  - `String` - set `origin` to a specific origin. For example if you set it to `"http://example.com"` only requests from "http://example.com" will be allowed.
-  - `RegExp` - set `origin` to a regular expression pattern which will be used to test the request origin. If it's a match, the request origin will be reflected. For example the pattern `/example\.com$/` will reflect any request that is coming from an origin ending with "example.com".
-  - `Array` - set `origin` to an array of valid origins. Each origin can be a `String` or a `RegExp`. For example `["http://example1.com", /\.example2\.com$/]` will accept any request from "http://example1.com" or from a subdomain of "example2.com".
-  - `Function` - set `origin` to a function implementing some custom logic. The function takes the request origin as the first parameter and a callback (which expects the signature `err [object], allow [bool]`) as the second.
-* `methods`: Configures the **Access-Control-Allow-Methods** CORS header. Expects a comma-delimited string (ex: 'GET,PUT,POST') or an array (ex: `['GET', 'PUT', 'POST']`).
-* `allowedHeaders`: Configures the **Access-Control-Allow-Headers** CORS header. Expects a comma-delimited string (ex: 'Content-Type,Authorization') or an array (ex: `['Content-Type', 'Authorization']`). If not specified, defaults to reflecting the headers specified in the request's **Access-Control-Request-Headers** header.
-* `exposedHeaders`: Configures the **Access-Control-Expose-Headers** CORS header. Expects a comma-delimited string (ex: 'Content-Range,X-Content-Range') or an array (ex: `['Content-Range', 'X-Content-Range']`). If not specified, no custom headers are exposed.
-* `credentials`: Configures the **Access-Control-Allow-Credentials** CORS header. Set to `true` to pass the header, otherwise it is omitted.
-* `maxAge`: Configures the **Access-Control-Max-Age** CORS header. Set to an integer to pass the header, otherwise it is omitted.
-* `preflightContinue`: Pass the CORS preflight response to the next handler.
-* `optionsSuccessStatus`: Provides a status code to use for successful `OPTIONS` requests, since some legacy browsers (IE11, various SmartTVs) choke on `204`.
-
-The default configuration is the equivalent of:
-
-```json
-{
-  "origin": "*",
-  "methods": "GET,HEAD,PUT,PATCH,POST,DELETE",
-  "preflightContinue": false,
-  "optionsSuccessStatus": 204
-}
-```
-
-For details on the effect of each CORS header, read [this](http://www.html5rocks.com/en/tutorials/cors/) article on HTML5 Rocks.
-
-## Demo
-
-A demo that illustrates CORS working (and not working) using jQuery is available here: [http://node-cors-client.herokuapp.com/](http://node-cors-client.herokuapp.com/)
-
-Code for that demo can be found here:
