+
+## Installing
+
+Using npm:
+
+```bash
+$ npm install axios
+```
+
+Using bower:
+
+```bash
+$ bower install axios
+```
+
+Using cdn:
+
+```html
+<script src="https://unpkg.com/axios/dist/axios.min.js"></script>
+```
+
+## Example
+
+Performing a `GET` request
+
+```js
+// Make a request for a user with a given ID
+axios.get('/user?ID=12345')
+  .then(function (response) {
+    console.log(response);
+  })
+  .catch(function (error) {
+    console.log(error);
+  });
+
+// Optionally the request above could also be done as
+axios.get('/user', {
+    params: {
+      ID: 12345
+    }
+  })
+  .then(function (response) {
+    console.log(response);
+  })
+  .catch(function (error) {
+    console.log(error);
+  });
+```
+
+Performing a `POST` request
+
+```js
+axios.post('/user', {
+    firstName: 'Fred',
+    lastName: 'Flintstone'
+  })
+  .then(function (response) {
+    console.log(response);
+  })
+  .catch(function (error) {
+    console.log(error);
+  });
+```
+
+Performing multiple concurrent requests
+
+```js
+function getUserAccount() {
+  return axios.get('/user/12345');
+}
+
+function getUserPermissions() {
+  return axios.get('/user/12345/permissions');
+}
+
+axios.all([getUserAccount(), getUserPermissions()])
+  .then(axios.spread(function (acct, perms) {
+    // Both requests are now complete
+  }));
+```
+
+## axios API
+
+Requests can be made by passing the relevant config to `axios`.
+
+##### axios(config)
+
+```js
+// Send a POST request
+axios({
+  method: 'post',
+  url: '/user/12345',
+  data: {
+    firstName: 'Fred',
+    lastName: 'Flintstone'
+  }
+});
+```
+
+```js
+// GET request for remote image
+axios({
+  method:'get',
+  url:'http://bit.ly/2mTM3nY',
+  responseType:'stream'
+})
+  .then(function(response) {
+  response.data.pipe(fs.createWriteStream('ada_lovelace.jpg'))
+});
+```
+
+##### axios(url[, config])
+
+```js
+// Send a GET request (default method)
+axios('/user/12345');
+```
+
+### Request method aliases
+
+For convenience aliases have been provided for all supported request methods.
+
+##### axios.request(config)
+##### axios.get(url[, config])
+##### axios.delete(url[, config])
+##### axios.head(url[, config])
+##### axios.options(url[, config])
+##### axios.post(url[, data[, config]])
+##### axios.put(url[, data[, config]])
+##### axios.patch(url[, data[, config]])
+
+###### NOTE
+When using the alias methods `url`, `method`, and `data` properties don't need to be specified in config.
+
+### Concurrency
+
+Helper functions for dealing with concurrent requests.
+
+##### axios.all(iterable)
+##### axios.spread(callback)
+
+### Creating an instance
+
+You can create a new instance of axios with a custom config.
+
+##### axios.create([config])
+
+```js
+var instance = axios.create({
+  baseURL: 'https://some-domain.com/api/',
+  timeout: 1000,
+  headers: {'X-Custom-Header': 'foobar'}
+});
+```
+
+### Instance methods
+
+The available instance methods are listed below. The specified config will be merged with the instance config.
+
+##### axios#request(config)
+##### axios#get(url[, config])
+##### axios#delete(url[, config])
+##### axios#head(url[, config])
+##### axios#options(url[, config])
+##### axios#post(url[, data[, config]])
+##### axios#put(url[, data[, config]])
+##### axios#patch(url[, data[, config]])
+
+## Request Config
+
+These are the available config options for making requests. Only the `url` is required. Requests will default to `GET` if `method` is not specified.
+
+```js
+{
+  // `url` is the server URL that will be used for the request
+  url: '/user',
+
+  // `method` is the request method to be used when making the request
+  method: 'get', // default
+
+  // `baseURL` will be prepended to `url` unless `url` is absolute.
+  // It can be convenient to set `baseURL` for an instance of axios to pass relative URLs
+  // to methods of that instance.
+  baseURL: 'https://some-domain.com/api/',
+
+  // `transformRequest` allows changes to the request data before it is sent to the server
+  // This is only applicable for request methods 'PUT', 'POST', and 'PATCH'
+  // The last function in the array must return a string or an instance of Buffer, ArrayBuffer,
+  // FormData or Stream
+  transformRequest: [function (data) {
+    // Do whatever you want to transform the data
+
+    return data;
+  }],
+
+  // `transformResponse` allows changes to the response data to be made before
+  // it is passed to then/catch
+  transformResponse: [function (data) {
+    // Do whatever you want to transform the data
+
+    return data;
+  }],
+
+  // `headers` are custom headers to be sent
+  headers: {'X-Requested-With': 'XMLHttpRequest'},
+
+  // `params` are the URL parameters to be sent with the request
+  // Must be a plain object or a URLSearchParams object
+  params: {
+    ID: 12345
+  },
+
+  // `paramsSerializer` is an optional function in charge of serializing `params`
+  // (e.g. https://www.npmjs.com/package/qs, http://api.jquery.com/jquery.param/)
+  paramsSerializer: function(params) {
+    return Qs.stringify(params, {arrayFormat: 'brackets'})
+  },
+
+  // `data` is the data to be sent as the request body
+  // Only applicable for request methods 'PUT', 'POST', and 'PATCH'
+  // When no `transformRequest` is set, must be of one of the following types:
+  // - string, plain object, ArrayBuffer, ArrayBufferView, URLSearchParams
+  // - Browser only: FormData, File, Blob
+  // - Node only: Stream, Buffer
+  data: {
+    firstName: 'Fred'
+  },
+
+  // `timeout` specifies the number of milliseconds before the request times out.
+  // If the request takes longer than `timeout`, the request will be aborted.
+  timeout: 1000,
+
+  // `withCredentials` indicates whether or not cross-site Access-Control requests
+  // should be made using credentials
+  withCredentials: false, // default
+
+  // `adapter` allows custom handling of requests which makes testing easier.
+  // Return a promise and supply a valid response (see lib/adapters/README.md).
+  adapter: function (config) {
+    /* ... */
+  },
+
+  // `auth` indicates that HTTP Basic auth should be used, and supplies credentials.
+  // This will set an `Authorization` header, overwriting any existing
+  // `Authorization` custom headers you have set using `headers`.
+  auth: {
+    username: 'janedoe',
+    password: 's00pers3cret'
+  },
+
+  // `responseType` indicates the type of data that the server will respond with
+  // options are 'arraybuffer', 'blob', 'document', 'json', 'text', 'stream'
+  responseType: 'json', // default
+
+  // `xsrfCookieName` is the name of the cookie to use as a value for xsrf token
+  xsrfCookieName: 'XSRF-TOKEN', // default
+
+  // `xsrfHeaderName` is the name of the http header that carries the xsrf token value
+  xsrfHeaderName: 'X-XSRF-TOKEN', // default
+
+  // `onUploadProgress` allows handling of progress events for uploads
+  onUploadProgress: function (progressEvent) {
+    // Do whatever you want with the native progress event
+  },
+
+  // `onDownloadProgress` allows handling of progress events for downloads
+  onDownloadProgress: function (progressEvent) {
+    // Do whatever you want with the native progress event
+  },
+
+  // `maxContentLength` defines the max size of the http response content allowed
+  maxContentLength: 2000,
+
+  // `validateStatus` defines whether to resolve or reject the promise for a given
+  // HTTP response status code. If `validateStatus` returns `true` (or is set to `null`
+  // or `undefined`), the promise will be resolved; otherwise, the promise will be
+  // rejected.
+  validateStatus: function (status) {
+    return status >= 200 && status < 300; // default
+  },
+
+  // `maxRedirects` defines the maximum number of redirects to follow in node.js.
+  // If set to 0, no redirects will be followed.
+  maxRedirects: 5, // default
+
+  // `httpAgent` and `httpsAgent` define a custom agent to be used when performing http
+  // and https requests, respectively, in node.js. This allows options to be added like
+  // `keepAlive` that are not enabled by default.
+  httpAgent: new http.Agent({ keepAlive: true }),
+  httpsAgent: new https.Agent({ keepAlive: true }),
+
+  // 'proxy' defines the hostname and port of the proxy server
+  // `auth` indicates that HTTP Basic auth should be used to connect to the proxy, and
+  // supplies credentials.
+  // This will set an `Proxy-Authorization` header, overwriting any existing
+  // `Proxy-Authorization` custom headers you have set using `headers`.
+  proxy: {
+    host: '127.0.0.1',
+    port: 9000,
+    auth: {
+      username: 'mikeymike',
+      password: 'rapunz3l'
+    }
+  },
+
+  // `cancelToken` specifies a cancel token that can be used to cancel the request
+  // (see Cancellation section below for details)
+  cancelToken: new CancelToken(function (cancel) {
+  })
+}
+```
+
+## Response Schema
+
+The response for a request contains the following information.
+
+```js
+{
+  // `data` is the response that was provided by the server
+  data: {},
+
+  // `status` is the HTTP status code from the server response
+  status: 200,
+
+  // `statusText` is the HTTP status message from the server response
+  statusText: 'OK',
+
+  // `headers` the headers that the server responded with
+  // All header names are lower cased
+  headers: {},
+
+  // `config` is the config that was provided to `axios` for the request
+  config: {},
+
+  // `request` is the request that generated this response
+  // It is the last ClientRequest instance in node.js (in redirects)
+  // and an XMLHttpRequest instance the browser
+  request: {}
+}
+```
+
+When using `then`, you will receive the response as follows:
+
+```js
+axios.get('/user/12345')
+  .then(function(response) {
+    console.log(response.data);
+    console.log(response.status);
+    console.log(response.statusText);
+    console.log(response.headers);
+    console.log(response.config);
+  });
+```
+
+When using `catch`, or passing a [rejection callback](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise/then) as second parameter of `then`, the response will be available through the `error` object as explained in the [Handling Errors](#handling-errors) section.
+
+## Config Defaults
+
+You can specify config defaults that will be applied to every request.
+
+### Global axios defaults
+
+```js
+axios.defaults.baseURL = 'https://api.example.com';
+axios.defaults.headers.common['Authorization'] = AUTH_TOKEN;
+axios.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded';
+```
+
+### Custom instance defaults
+
+```js
+// Set config defaults when creating the instance
+var instance = axios.create({
+  baseURL: 'https://api.example.com'
+});
+
+// Alter defaults after instance has been created
+instance.defaults.headers.common['Authorization'] = AUTH_TOKEN;
+```
+
+### Config order of precedence
+
+Config will be merged with an order of precedence. The order is library defaults found in `lib/defaults.js`, then `defaults` property of the instance, and finally `config` argument for the request. The latter will take precedence over the former. Here's an example.
+
+```js
+// Create an instance using the config defaults provided by the library
+// At this point the timeout config value is `0` as is the default for the library
+var instance = axios.create();
+
+// Override timeout default for the library
+// Now all requests will wait 2.5 seconds before timing out
+instance.defaults.timeout = 2500;
+
+// Override timeout for this request as it's known to take a long time
+instance.get('/longRequest', {
+  timeout: 5000
+});
+```
+
+## Interceptors
+
+You can intercept requests or responses before they are handled by `then` or `catch`.
+
+```js
+// Add a request interceptor
+axios.interceptors.request.use(function (config) {
+    // Do something before request is sent
+    return config;
+  }, function (error) {
+    // Do something with request error
+    return Promise.reject(error);
+  });
+
+// Add a response interceptor
+axios.interceptors.response.use(function (response) {
+    // Do something with response data
+    return response;
+  }, function (error) {
+    // Do something with response error
+    return Promise.reject(error);
+  });
+```
+
+If you may need to remove an interceptor later you can.
+
+```js
+var myInterceptor = axios.interceptors.request.use(function () {/*...*/});
+axios.interceptors.request.eject(myInterceptor);
+```
+
+You can add interceptors to a custom instance of axios.
+
+```js
+var instance = axios.create();
+instance.interceptors.request.use(function () {/*...*/});
+```
+
+## Handling Errors
+
+```js
+axios.get('/user/12345')
+  .catch(function (error) {
+    if (error.response) {
+      // The request was made and the server responded with a status code
+      // that falls out of the range of 2xx
+      console.log(error.response.data);
+      console.log(error.response.status);
+      console.log(error.response.headers);
+    } else if (error.request) {
+      // The request was made but no response was received
+      // `error.request` is an instance of XMLHttpRequest in the browser and an instance of
+      // http.ClientRequest in node.js
+      console.log(error.request);
+    } else {
+      // Something happened in setting up the request that triggered an Error
+      console.log('Error', error.message);
+    }
+    console.log(error.config);
+  });
+```
+
+You can define a custom HTTP status code error range using the `validateStatus` config option.
+
+```js
+axios.get('/user/12345', {
+  validateStatus: function (status) {
+    return status < 500; // Reject only if the status code is greater than or equal to 500
+  }
+})
+```
+
+## Cancellation
+
+You can cancel a request using a *cancel token*.
+
+> The axios cancel token API is based on the withdrawn [cancelable promises proposal](https://github.com/tc39/proposal-cancelable-promises).
+
+You can create a cancel token using the `CancelToken.source` factory as shown below:
+
+```js
+var CancelToken = axios.CancelToken;
+var source = CancelToken.source();
+
+axios.get('/user/12345', {
+  cancelToken: source.token
+}).catch(function(thrown) {
+  if (axios.isCancel(thrown)) {
+    console.log('Request canceled', thrown.message);
+  } else {
+    // handle error
+  }
+});
+
+// cancel the request (the message parameter is optional)
+source.cancel('Operation canceled by the user.');
+```
+
+You can also create a cancel token by passing an executor function to the `CancelToken` constructor:
+
+```js
+var CancelToken = axios.CancelToken;
+var cancel;
+
+axios.get('/user/12345', {
+  cancelToken: new CancelToken(function executor(c) {
+    // An executor function receives a cancel function as a parameter
+    cancel = c;
+  })
+});
+
+// cancel the request
+cancel();
+```
+
+> Note: you can cancel several requests with the same cancel token.
+
+## Using application/x-www-form-urlencoded format
+
+By default, axios serializes JavaScript objects to `JSON`. To send data in the `application/x-www-form-urlencoded` format instead, you can use one of the following options.
+
+### Browser
+
+In a browser, you can use the [`URLSearchParams`](https://developer.mozilla.org/en-US/docs/Web/API/URLSearchParams) API as follows:
+
+```js
+var params = new URLSearchParams();
+params.append('param1', 'value1');
+params.append('param2', 'value2');
+axios.post('/foo', params);
+```
+
+> Note that `URLSearchParams` is not supported by all browsers, but there is a [polyfill](https://github.com/WebReflection/url-search-params) available (make sure to polyfill the global environment).
+
+Alternatively, you can encode data using the [`qs`](https://github.com/ljharb/qs) library:
+
+```js
+var qs = require('qs');
+axios.post('/foo', qs.stringify({ 'bar': 123 }));
+```
+
+### Node.js
+
+In node.js, you can use the [`querystring`](https://nodejs.org/api/querystring.html) module as follows:
+
+```js
+var querystring = require('querystring');
+axios.post('http://something.com/', querystring.stringify({ foo: 'bar' }));
+```
+
+You can also use the `qs` library.
+
+## Semver
+
+Until axios reaches a `1.0` release, breaking changes will be released with a new minor version. For example `0.5.1`, and `0.5.4` will have the same API, but `0.6.0` will have breaking changes.
+
+## Promises
+
+axios depends on a native ES6 Promise implementation to be [supported](http://caniuse.com/promises).
+If your environment doesn't support ES6 Promises, you can [polyfill](https://github.com/jakearchibald/es6-promise).
+
+## TypeScript
+axios includes [TypeScript](http://typescriptlang.org) definitions.
+```typescript
+import axios from 'axios';
+axios.get('/user?ID=12345');
+```

+## Credits
+
+axios is heavily inspired by the [$http service](https://docs.angularjs.org/api/ng/service/$http) provided in [Angular](https://angularjs.org/). Ultimately axios is an effort to provide a standalone `$http`-like service for use outside of Angular.

+# Upgrade Guide
+
+### 0.15.x -> 0.16.0
+
+#### `Promise` Type Declarations
+
+The `Promise` type declarations have been removed from the axios typings in favor of the built-in type declarations. If you use axios in a TypeScript project that targets `ES5`, please make sure to include the `es2015.promise` lib. Please see [this post](https://blog.mariusschulz.com/2016/11/25/typescript-2-0-built-in-type-declarations) for details.
+
+### 0.13.x -> 0.14.0
+
+#### TypeScript Definitions
+
+The axios TypeScript definitions have been updated to match the axios API and use the ES2015 module syntax.
+
+Please use the following `import` statement to import axios in TypeScript:
+
+```typescript
+import axios from 'axios';
+
+axios.get('/foo')
+  .then(response => console.log(response))
+  .catch(error => console.log(error));
+```
+
+#### `agent` Config Option
+
+The `agent` config option has been replaced with two new options: `httpAgent` and `httpsAgent`. Please use them instead.
+
+```js
+{
+  // Define a custom agent for HTTP
+  httpAgent: new http.Agent({ keepAlive: true }),
+  // Define a custom agent for HTTPS
+  httpsAgent: new https.Agent({ keepAlive: true })
+}
+```
+
+#### `progress` Config Option
+
+The `progress` config option has been replaced with the `onUploadProgress` and `onDownloadProgress` options.
+
+```js
+{
+  // Define a handler for upload progress events
+  onUploadProgress: function (progressEvent) {
+    // ...
+  },
+
+  // Define a handler for download progress events
+  onDownloadProgress: function (progressEvent) {
+    // ...
+  }
+}
+```
+
+### 0.12.x -> 0.13.0
+
+The `0.13.0` release contains several changes to custom adapters and error handling.
+
+#### Error Handling
+
+Previous to this release an error could either be a server response with bad status code or an actual `Error`. With this release Promise will always reject with an `Error`. In the case that a response was received, the `Error` will also include the response.
+
+```js
+axios.get('/user/12345')
+  .catch((error) => {
+    console.log(error.message);
+    console.log(error.code); // Not always specified
+    console.log(error.config); // The config that was used to make the request
+    console.log(error.response); // Only available if response was received from the server
+  });
+```
+
+#### Request Adapters
+
+This release changes a few things about how request adapters work. Please take note if you are using your own custom adapter.
+
+1. Response transformer is now called outside of adapter.
+2. Request adapter returns a `Promise`.
+
+This means that you no longer need to invoke `transformData` on response data. You will also no longer receive `resolve` and `reject` as arguments in your adapter.
+
+Previous code:
+
+```js
+function myAdapter(resolve, reject, config) {
+  var response = {
+    data: transformData(
+      responseData,
+      responseHeaders,
+      config.transformResponse
+    ),
+    status: request.status,
+    statusText: request.statusText,
+    headers: responseHeaders
+  };
+  settle(resolve, reject, response);
+}
+```
+
+New code:
+
+```js
+function myAdapter(config) {
+  return new Promise(function (resolve, reject) {
+    var response = {
+      data: responseData,
+      status: request.status,
+      statusText: request.statusText,
+      headers: responseHeaders
+    };
+    settle(resolve, reject, response);
+  });
+}
+```
+

+
+### 0.5.x -> 0.6.0
+
+The `0.6.0` release contains mostly bug fixes, but there are a couple things to be aware of when upgrading.
+
+#### ES6 Promise Polyfill
+
+Up until the `0.6.0` release ES6 `Promise` was being polyfilled using [es6-promise](https://github.com/jakearchibald/es6-promise). With this release, the polyfill has been removed, and you will need to supply it yourself if your environment needs it.
+
+```js
+require('es6-promise').polyfill();
+var axios = require('axios');
+```
+
+This will polyfill the global environment, and only needs to be done once.
+
+#### `axios.success`/`axios.error`
+
+The `success`, and `error` aliases were deprectated in [0.4.0](https://github.com/mzabriskie/axios/blob/master/CHANGELOG.md#040-oct-03-2014). As of this release they have been removed entirely. Instead please use `axios.then`, and `axios.catch` respectively.
+
+```js
+axios.get('some/url')
+  .then(function (res) {
+    /* ... */
+  })
+  .catch(function (err) {
+    /* ... */
+  });
+```
+
+#### UMD
+
+Previous versions of axios shipped with an AMD, CommonJS, and Global build. This has all been rolled into a single UMD build.
+
+```js
+// AMD
+require(['bower_components/axios/dist/axios'], function (axios) {
+  /* ... */
+});
+
+// CommonJS
+var axios = require('axios/dist/axios');
+```

+## Follow Redirects
+
+Drop-in replacement for Nodes `http` and `https` that automatically follows redirects.

+[![devDependency Status](https://david-dm.org/olalonde/follow-redirects/dev-status.svg)](https://david-dm.org/olalonde/follow-redirects#info=devDependencies)
+
+[![NPM](https://nodei.co/npm/follow-redirects.png?downloads=true)](https://nodei.co/npm/follow-redirects/)
+
+`follow-redirects` provides [request](https://nodejs.org/api/http.html#http_http_request_options_callback) and [get](https://nodejs.org/api/http.html#http_http_get_options_callback)
+ methods that behave identically to those found on the native [http](https://nodejs.org/api/http.html#http_http_request_options_callback) and [https](https://nodejs.org/api/https.html#https_https_request_options_callback)
+ modules, with the exception that they will seamlessly follow redirects.
+
+```javascript
+var http = require('follow-redirects').http;
+var https = require('follow-redirects').https;
+
+http.get('http://bit.ly/900913', function (response) {
+  response.on('data', function (chunk) {
+    console.log(chunk);
+  });
+}).on('error', function (err) {
+  console.error(err);
+});
+```
+
+You can inspect the final redirected URL through the `responseUrl` property on the `response`.
+If no redirection happened, `responseUrl` is the original request URL.
+
+```javascript
+https.request({
+  host: 'bitly.com',
+  path: '/UHfDGO',
+}, function (response) {
+  console.log(response.responseUrl);
+  // 'http://duckduckgo.com/robots.txt'
+});
+```
+
+## Options
+### Global options
+Global options are set directly on the `follow-redirects` module:
+
+```javascript
+var followRedirects = require('follow-redirects');
+followRedirects.maxRedirects = 10;
+```
+
+The following global options are supported:
+
+- `maxRedirects` (default: `21`) – sets the maximum number of allowed redirects; if exceeded, an error will be emitted.
+
+
+### Per-request options
+Per-request options are set by passing an `options` object:
+
+```javascript
+var url = require('url');
+var followRedirects = require('follow-redirects');
+
+var options = url.parse('http://bit.ly/900913');
+options.maxRedirects = 10;
+http.request(options);
+```
+
+In addition to the [standard HTTP](https://nodejs.org/api/http.html#http_http_request_options_callback) and [HTTPS options](https://nodejs.org/api/https.html#https_https_request_options_callback),
+the following per-request options are supported:
+- `followRedirects` (default: `true`) – whether redirects should be followed.
+
+- `maxRedirects` (default: `21`) – sets the maximum number of allowed redirects; if exceeded, an error will be emitted.
+
+- `agents` (default: `undefined`) – sets the `agent` option per protocol, since HTTP and HTTPS use different agents. Example value: `{ http: new http.Agent(), https: new https.Agent() }`
+
+
+## Browserify Usage
+
+Due to the way `XMLHttpRequest` works, the `browserify` versions of `http` and `https` already follow redirects.
+ If you are *only* targeting the browser, then this library has little value for you. If you want to write cross
+ platform code for node and the browser, `follow-redirects` provides a great solution for making the native node
+ modules behave the same as they do in browserified builds in the browser. To avoid bundling unnecessary code
+ you should tell browserify to swap out `follow-redirects` with the standard modules when bundling.
+ To make this easier, you need to change how you require the modules:
+
+```javascript
+var http = require('follow-redirects/http');
+var https = require('follow-redirects/https');
+```
+
+You can then replace `follow-redirects` in your browserify configuration like so:
+
+```javascript
+"browser": {
+  "follow-redirects/http"  : "http",
+  "follow-redirects/https" : "https"
+}
+```
+
+The `browserify-http` module has not kept pace with node development, and no long behaves identically to the native
+ module when running in the browser. If you are experiencing problems, you may want to check out
+ [browserify-http-2](https://www.npmjs.com/package/http-browserify-2). It is more actively maintained and
+ attempts to address a few of the shortcomings of `browserify-http`. In that case, your browserify config should
+ look something like this:
+
+```javascript
+"browser": {
+  "follow-redirects/http"  : "browserify-http-2/http",
+  "follow-redirects/https" : "browserify-http-2/https"
+}
+```
+
+## Contributing
+
+Pull Requests are always welcome. Please [file an issue](https://github.com/olalonde/follow-redirects/issues)
+ detailing your proposal before you invest your valuable time. Additional features and bug fixes should be accompanied
+ by tests. You can run the test suite locally with a simple `npm test` command.
+
+## Debug Logging
+
+`follow-redirects` uses the excellent [debug](https://www.npmjs.com/package/debug) for logging. To turn on logging
+ set the environment variable `DEBUG=follow-redirects` for debug output from just this module. When running the test
+ suite it is sometimes advantageous to set `DEBUG=*` to see output from the express server as well.
