+
+[![Build Status](https://travis-ci.org/przemyslawpluta/node-youtube-dl.svg?branch=master)](https://travis-ci.org/przemyslawpluta/node-youtube-dl) [![npm version](https://badge.fury.io/js/youtube-dl.svg)](https://badge.fury.io/js/youtube-dl)
+
+Download videos from youtube in node.js using [youtube-dl](http://rg3.github.com/youtube-dl/).
+
+If you're only interested in downloading only from youtube, you should consider using [pure Javascript youtube downloading module](https://github.com/fent/node-ytdl).
+
+## Installation
+
+With [npm](https://www.npmjs.com/) do:
+
+``` sh
+npm install @microlink/youtube-dl
+```
+
+## Usage
+
+### Downloading videos
+
+``` js
+var fs = require('fs');
+var youtubedl = require('youtube-dl');
+var video = youtubedl('http://www.youtube.com/watch?v=90AiXO1pAiA',
+  // Optional arguments passed to youtube-dl.
+  ['--format=18'],
+  // Additional options can be given for calling `child_process.execFile()`.
+  { cwd: __dirname });
+
+// Will be called when the download starts.
+video.on('info', function(info) {
+  console.log('Download started');
+  console.log('filename: ' + info._filename);
+  console.log('size: ' + info.size);
+});
+
+video.pipe(fs.createWriteStream('myvideo.mp4'));
+```
+
+It will produce an output that looks like the following when ran.
+
+```bash
+Got video info
+saving to T-ara - Number Nine - MV - 티아라-Seku9G1kT0c.mp4
+100.00%
+```
+
+### Resuming partially downloaded videos
+
+``` js
+var youtubedl = require('./');
+var fs = require('fs');
+var output = 'myvideo.mp4';
+
+var downloaded = 0;
+if (fs.existsSync(output)) {
+  downloaded = fs.statSync(output).size;
+}
+
+var video = youtubedl('https://www.youtube.com/watch?v=179MiZSibco',
+
+  // Optional arguments passed to youtube-dl.
+  ['--format=18'],
+
+  // start will be sent as a range header
+  { start: downloaded, cwd: __dirname });
+
+// Will be called when the download starts.
+video.on('info', function(info) {
+  console.log('Download started');
+  console.log('filename: ' + info._filename);
+
+  // info.size will be the amount to download, add
+  var total = info.size + downloaded;
+  console.log('size: ' + total);
+
+  if (downloaded > 0) {
+    // size will be the amount already downloaded
+    console.log('resuming from: ' + downloaded);
+
+    // display the remaining bytes to download
+    console.log('remaining bytes: ' + info.size);
+  }
+});
+
+video.pipe(fs.createWriteStream('myvideo.mp4', { flags: 'a' }));
+
+// Will be called if download was already completed and there is nothing more to download.
+video.on('complete', function complete(info) {
+  'use strict';
+  console.log('filename: ' + info._filename + ' already downloaded.');
+});
+
+video.on('end', function() {
+  console.log('finished downloading!');
+});
+```
+
+It will produce an output that looks like the following when ran.
+
+**Output:**
+
+``` sh
+[~/nodejs/node-youtube-dl/example]$ node resume.js
+Download started
+filename: 1 1 1-179MiZSibco.mp4
+size: 5109213
+^C
+```
+
+``` sh
+[~/nodejs/node-youtube-dl/example]$ node resume.js
+Download started
+filename: 1 1 1-179MiZSibco.mp4
+size: 5109213
+resuming from: 917504
+remaining bytes: 4191709
+finished downloading
+```
+
+### Getting video information
+
+``` js
+var youtubedl = require('youtube-dl');
+var url = 'http://www.youtube.com/watch?v=WKsjaOqDXgg';
+// Optional arguments passed to youtube-dl.
+var options = ['--username=user', '--password=hunter2'];
+youtubedl.getInfo(url, options, function(err, info) {
+  if (err) throw err;
+
+  console.log('id:', info.id);
+  console.log('title:', info.title);
+  console.log('url:', info.url);
+  console.log('thumbnail:', info.thumbnail);
+  console.log('description:', info.description);
+  console.log('filename:', info._filename);
+  console.log('format id:', info.format_id);
+});
+```
+
+Running that will produce something like
+
+``` sh
+id: WKsjaOqDXgg

+
+You can use an array of urls to produce an array of response objects with matching array index (e.g. the 1st response object will match the first url etc...)
+
+``` js
+var youtubedl = require('youtube-dl');
+var url1 = 'http://www.youtube.com/watch?v=WKsjaOqDXgg';
+var url2 = 'https://vimeo.com/6586873';
+youtubedl.getInfo([url1, url2], function(err, info) {
+  if (err) throw err;
+
+  console.log('title for the url1:', info[0].title);
+  console.log('title for the url2:', info[1].title);
+});
+```
+
+### Downloading subtitles
+
+``` js
+var youtubedl = require('youtube-dl');
+var url = 'https://youtu.be/PizwcirYuGY';
+
+var options = {
+  // Write automatic subtitle file (youtube only)
+  auto: false,
+  // Downloads all the available subtitles.
+  all: false,
+  // Subtitle format. YouTube generated subtitles
+  // are available ttml or vtt.
+  format: 'ttml',
+  // Languages of subtitles to download, separated by commas.
+  lang: 'en',
+  // The directory to save the downloaded files in.
+  cwd: __dirname,
+};
+youtubedl.getSubs(url, options, function(err, files) {
+  if (err) throw err;
+
+  console.log('subtitle files downloaded:', files);
+});
+```
+
+### Downloading thumbnails
+
+``` js
+var youtubedl = require('youtube-dl');
+var url = 'https://youtu.be/PizwcirYuGY';
+
+var options = {
+  // Downloads available thumbnail.
+  all: false,

+};
+youtubedl.getThumbs(url, options, function(err, files) {
+  if (err) throw err;
+  console.log('thumbnail file downloaded:', files);
+});
+```
+
+For more usage info on youtube-dl and the arguments you can pass to it, do `youtube-dl -h` or go to the [youtube-dl documentation][].
+
+### Downloading playlists

+### Getting the list of extractors
+
+``` js
+var youtubedl = require('youtube-dl');
+youtubedl.getExtractors(true, function(err, list) {
+  console.log('Found ' + list.length + ' extractors');
+  for (var i = 0; i < list.length; i++) {
+    console.log(list[i]);
+  }
+});
+```
+
+Will print something like
+
+``` sh
+Found 521 extractors
+1up.com
+220.ro
+24video
+3sat
+```
+
+### Call the `youtube-dl` binary directly
+
+This module doesn't have `youtube-dl` download the video. Instead, it uses the `url` key from the `--dump-json` CLI option to create a node stream. That way, it can be used like any other node stream.
+
+If that, or none of the above support your use case, you can use `ytdl.exec()` to call `youtube-dl` however you like.
+
+``` js
+ytdl.exec(url, ['-x', '--audio-format', 'mp3'], {}, function(err, output) {
+  if (err) throw err;
+  console.log(output.join('\n'));
+});
+```
+
+### Update
+
+Since the youtube-dl binary is updated regularly, you can run `npm run update` to check for and download any updates for it. You can also require `../lib/downloader` in your app if you'd like to place `youtube-dl` binary in a specific directory and control when it gets updates.
+
+``` js
+var downloader = require('../lib/downloader');
+
+downloader('path/to-binary', function error(err, done) {
+  'use strict';
+  if (err) { return console.log(err.stack); }
+  console.log(done);
+});
+```
+
+### Tests
+
+Tests are written with [vows](http://vowsjs.org/)
+
+``` sh
+npm test
+```

+Hashish
+=======
+
+Hashish is a node.js library for manipulating hash data structures.
+It is distilled from the finest that ruby, perl, and haskell have to offer by
+way of hash/map interfaces.
+
+Hashish provides a chaining interface, where you can do:
+
+    var Hash = require('hashish');
+    
+    Hash({ a : 1, b : 2, c : 3, d : 4 })
+        .map(function (x) { return x * 10 })
+        .filter(function (x) { return x < 30 })
+        .forEach(function (x, key) {
+            console.log(key + ' => ' + x);
+        })
+    ;
+    
+Output:
+
+    a => 10
+    b => 20
+
+Some functions and attributes in the chaining interface are terminal, like
+`.items` or `.detect()`. They return values of their own instead of the chain
+context.
+
+Each function in the chainable interface is also attached to `Hash` in chainless
+form:
+
+    var Hash = require('hashish');
+    var obj = { a : 1, b : 2, c : 3, d : 4 };
+    
+    var mapped = Hash.map(obj, function (x) {
+        return x * 10
+    });
+    
+    console.dir(mapped);
+
+Output:
+
+    { a: 10, b: 20, c: 30, d: 40 }
+
+In either case, the 'this' context of the function calls is the same object that
+the chained functions return, so you can make nested chains.
+
+Methods
+=======
+
+forEach(cb)
+-----------
+
+For each key/value in the hash, calls `cb(value, key)`.
+
+map(cb)
+-------
+
+For each key/value in the hash, calls `cb(value, key)`.
+The return value of `cb` is the new value at `key` in the resulting hash.
+
+filter(cb)
+----------
+
+For each key/value in the hash, calls `cb(value, key)`.
+The resulting hash omits key/value pairs where `cb` returned a falsy value.
+
+detect(cb)
+----------
+
+Returns the first value in the hash for which `cb(value, key)` is non-falsy.
+Order of hashes is not well-defined so watch out for that.
+
+reduce(cb)
+----------
+
+Returns the accumulated value of a left-fold over the key/value pairs.
+
+some(cb)
+--------
+
+Returns a boolean: whether or not `cb(value, key)` ever returned a non-falsy
+value.
+
+update(obj1, [obj2, obj3, ...])
+-----------
+
+Mutate the context hash, merging the key/value pairs from the passed objects
+and overwriting keys from the context hash if the current `obj` has keys of
+the same name. Falsy arguments are silently ignored.
+
+updateAll([ obj1, obj2, ... ])
+------------------------------
+
+Like multi-argument `update()` but operate on an array directly.
+
+merge(obj1, [obj2, obj3, ...])
+----------
+
+Merge the key/value pairs from the passed objects into the resultant hash
+without modifying the context hash. Falsy arguments are silently ignored.
+
+mergeAll([ obj1, obj2, ... ])
+------------------------------
+
+Like multi-argument `merge()` but operate on an array directly.
+
+has(key)
+--------
+
+Return whether the hash has a key, `key`.
+
+valuesAt(keys)
+--------------
+
+Return an Array with the values at the keys from `keys`.
+
+tap(cb)
+-------
+
+Call `cb` with the present raw hash.
+This function is chainable.
+
+extract(keys)
+-------------
+
+Filter by including only those keys in `keys` in the resulting hash.
+
+exclude(keys)
+-------------
+
+Filter by excluding those keys in `keys` in the resulting hash.
+
+Attributes
+==========
+
+These are attributes in the chaining interface and functions in the `Hash.xxx`
+interface.
+
+keys
+----
+
+Return all the enumerable attribute keys in the hash.
+
+values
+------
+
+Return all the enumerable attribute values in the hash.
+
+compact
+-------
+
+Filter out values which are `=== undefined`.
+
+clone
+-----
+
+Make a deep copy of the hash.
+
+copy
+----
+
+Make a shallow copy of the hash.
+
+length
+------
+
+Return the number of key/value pairs in the hash.
+Note: use `Hash.size()` for non-chain mode.
+
+size
+----
+
+Alias for `length` since `Hash.length` is masked by `Function.prototype`.
+

+See also [creationix's pattern/hash](http://github.com/creationix/pattern),
+which does a similar thing except with hash inputs and array outputs.

+[![js-standard-style](https://img.shields.io/badge/code%20style-standard-brightgreen.svg)](http://standardjs.com/)
+
+
+:watch: Convert seconds or miliseconds to `hh:mm:ss` format and vice versa.
+
+```js
+var TimeFormat = require('hh-mm-ss')
+
+TimeFormat.toS('137:00:00')            // 493200
+TimeFormat.toS('02:00')                // 120
+TimeFormat.toS('02:00', 'hh:mm')       // 7200
+
+TimeFormat.fromS(194)                  // '03:14'
+TimeFormat.fromS(150, 'hh:mm:ss')      // '00:02:30'
+TimeFormat.fromS(8100, 'hh:mm')        // '02:15'
+
+TimeFormat.fromMs(12345)               // '00:12.345'
+```
+
+## Usage
+
+### `toMs(time, format)`
+
+Convert given `hh:mm:ss` formatted string to miliseconds
+
+#### Parameters
+- `time` String representation
+- `format` _(optional)_ Default input format. If present, it will be used to resolve amiguities during interpretation. If not specified, `mm:ss` is implied. See section below for supported format list
+
+### `toS(time, format)`
+
+Convert given `hh:mm:ss` formatted string to seconds
+
+#### Parameters
+- `time` String representation
+- `format` _(optional)_ Default input format. If present, it will be used to resolve amiguities during interpretation. If not specified, `mm:ss` is implied. See section below for supported format list
+
+### `fromMs(ms, format)`
+
+Generate formatted string from time in miliseconds
+
+#### Parameters
+- `ms` Time in miliseconds
+- `format` _(optional)_ Default output format. If not specified, `mm:ss` is implied. See section below for supported format list.
+
+### `fromS(s, format)`
+
+Generate formatted string from time in seconds
+
+#### Parameters
+- `s` Time in seconds
+- `format` _(optional)_ Default output format. If not specified, `mm:ss` is implied. See section below for supported format list
+
+### Supported time formats
+The following formats are supported: `mm:ss`, `hh:mm`, `hh:mm:ss`, `mm:ss.sss`, `hh:mm:ss.sss`.
+
+- `hh` - hours
+- `mm` - minutes
+- `ss` - second
+- `sss` - miliseconds
+
+Specified format constitutes a baseline for corresponding functions, but will be appropriately extended as needed. For example, `fromMs(9000, 'mm:ss')` will return `01:30`, yet `fromMs(9500, 'mm:ss')` will return `01:30.500` to account for the miliseconds part.

+parse argument options
+
+This module is the guts of optimist's argument parser without all the
+fanciful decoration.

+# example
+
+``` js
+var argv = require('minimist')(process.argv.slice(2));
+console.dir(argv);
+```
+
+```
+$ node example/parse.js -a beep -b boop
+{ _: [], a: 'beep', b: 'boop' }
+```
+
+```
+$ node example/parse.js -x 3 -y 4 -n5 -abc --beep=boop foo bar baz
+{ _: [ 'foo', 'bar', 'baz' ],
+  x: 3,
+  y: 4,
+  n: 5,
+  a: true,
+  b: true,
+  c: true,
+  beep: 'boop' }
+```
+
+# methods
+
+``` js
+var parseArgs = require('minimist')
+```
+
+## var argv = parseArgs(args, opts={})
+
+Return an argument object `argv` populated with the array arguments from `args`.
+
+`argv._` contains all the arguments that didn't have an option associated with
+them.
+
+Numeric-looking arguments will be returned as numbers unless `opts.string` or
+`opts.boolean` is set for that argument name.
+
+Any arguments after `'--'` will not be parsed and will end up in `argv._`.
+
+options can be:
+
+* `opts.string` - a string or array of strings argument names to always treat as
+strings
+* `opts.boolean` - a string or array of strings to always treat as booleans
+* `opts.alias` - an object mapping string names to strings or arrays of string
+argument names to use as aliases
+* `opts.default` - an object mapping string argument names to default values

+# mkdirp
+
+Like `mkdir -p`, but in node.js!
+
+[![build status](https://secure.travis-ci.org/substack/node-mkdirp.png)](http://travis-ci.org/substack/node-mkdirp)
+
+# example
+
+## pow.js
+
+```js
+var mkdirp = require('mkdirp');
+    
+mkdirp('/tmp/foo/bar/baz', function (err) {
+    if (err) console.error(err)
+    else console.log('pow!')
+});
+```
+
+Output
+
+```
+pow!
+```
+
+And now /tmp/foo/bar/baz exists, huzzah!
+
+# methods
+
+```js
+var mkdirp = require('mkdirp');
+```
+
+## mkdirp(dir, opts, cb)
+
+Create a new directory and any necessary subdirectories at `dir` with octal
+permission string `opts.mode`. If `opts` is a non-object, it will be treated as
+the `opts.mode`.
+
+If `opts.mode` isn't specified, it defaults to `0777 & (~process.umask())`.
+
+`cb(err, made)` fires with the error or the first directory `made`
+that had to be created, if any.
+
+You can optionally pass in an alternate `fs` implementation by passing in
+`opts.fs`. Your implementation should have `opts.fs.mkdir(path, mode, cb)` and
+`opts.fs.stat(path, cb)`.
+
+## mkdirp.sync(dir, opts)
+
+Synchronously create a new directory and any necessary subdirectories at `dir`
+with octal permission string `opts.mode`. If `opts` is a non-object, it will be
+treated as the `opts.mode`.
+
+If `opts.mode` isn't specified, it defaults to `0777 & (~process.umask())`.
+
+Returns the first directory that had to be created, if any.
+
+You can optionally pass in an alternate `fs` implementation by passing in
+`opts.fs`. Your implementation should have `opts.fs.mkdirSync(path, mode)` and
+`opts.fs.statSync(path)`.
+
+# usage
+
+This package also ships with a `mkdirp` command.
+
+```
+usage: mkdirp [DIR1,DIR2..] {OPTIONS}
+
+  Create each supplied directory including any necessary parent directories that
+  don't yet exist.
+  
+  If the directory already exists, do nothing.
+
+OPTIONS are:
+
+  -m, --mode   If a directory needs to be created, set the mode as an octal

+
+Streamify helps you easily provide a streaming interface for your code.
+
+[![Build Status](https://secure.travis-ci.org/fent/node-streamify.svg)](http://travis-ci.org/fent/node-streamify)
+[![Dependency Status](https://david-dm.org/fent/node-streamify.svg)](https://david-dm.org/fent/node-streamify)
+[![codecov](https://codecov.io/gh/fent/node-streamify/branch/master/graph/badge.svg)](https://codecov.io/gh/fent/node-streamify)
+
+# Usage
+
+```js
+var streamify = require('streamify');
+var request   = require('request');
+
+exports.doSomething = function doSomething() {
+  var stream = streamify();
+
+  request(url1, function(err, res, body) {
+    // do something with `body`
+
+    // once the actual stream you want to return is ready,
+    // call `stream.resolve()`
+    stream.resolve(request(url2));
+  });
+
+  // your function can return back a stream!!
+  return stream;
+}
+
+// because `doSomething()` returns a stream, it can be piped
+exports.doSomething().pipe(anotherStream);
+```
+
+
+# API
+### streamify([options])
+
+Returns an instance of a stream. `options` can be
+
+* `superCtor` - The object from which it inherits. Defaults to `require('stream').Stream`. Sometimes you may want to use this if your stream might be checked with the `instanceof` operator against objects such as `http.ServerResponse`.
+* `readable` - Defaults to `true`.
+* `writable` - Defaults to `true`.
+
+### Stream#resolve(stream)
+
+Must be called only once when the actual stream you are proxying to becomes available after an asynchronous operation.
+
+### Stream#unresolve()
+
+Can be used to unbind a a resolved stream to later call `resolve()` again.
+
+### Stream#addSource(stream)
+
+Add a source readable stream.
+
+### Stream#removeSource()
+
+Remove previously added source stream.
+
+### Stream#addDest(stream)
+
+Add a destination writable stream.
+
+### Stream#removeDest()
+
+Remove a previously added destination stream.
+
+
+# Install
+

+
+# methods
+
+Each method that takes an `fn` uses the context documented below in the context
+section.
+
+## .map(fn)
+
+Execute `fn` for each node in the object and return a new object with the
+results of the walk. To update nodes in the result use `this.update(value)`.
+
+## .forEach(fn)
+
+Execute `fn` for each node in the object but unlike `.map()`, when
+`this.update()` is called it updates the object in-place.
+
+## .reduce(fn, acc)
+
+For each node in the object, perform a
+[left-fold](http://en.wikipedia.org/wiki/Fold_(higher-order_function))
+with the return value of `fn(acc, node)`.
+
+If `acc` isn't specified, `acc` is set to the root object for the first step
+and the root element is skipped.
+
+## .paths()
+
+Return an `Array` of every possible non-cyclic path in the object.
+Paths are `Array`s of string keys.
+
+## .nodes()
+
+Return an `Array` of every node in the object.
+
+## .clone()
+
+Create a deep clone of the object.
+
+## .get(path)
+
+Get the element at the array `path`.
+
+## .set(path, value)
+
+Set the element at the array `path` to `value`.
+
+## .has(path)
+
+Return whether the element at the array `path` exists.
+
+# context
+
+Each method that takes a callback has a context (its `this` object) with these
+attributes:
+
+## this.node
+
+The present node on the recursive walk
+
+## this.path
+
+An array of string keys from the root to the present node
+
+## this.parent
+
+The context of the node's parent.
+This is `undefined` for the root node.
+
+## this.key
+
+The name of the key of the present node in its parent.
+This is `undefined` for the root node.
+
+## this.isRoot, this.notRoot
+
+Whether the present node is the root node
+
+## this.isLeaf, this.notLeaf
+
+Whether or not the present node is a leaf node (has no children)
+
+## this.level
+
+Depth of the node within the traversal
+
+## this.circular
+
+If the node equals one of its parents, the `circular` attribute is set to the
+context of that parent and the traversal progresses no deeper.
+
+## this.update(value, stopHere=false)
+
+Set a new value for the present node.
+
+All the elements in `value` will be recursively traversed unless `stopHere` is
+true.
+
+## this.remove(stopHere=false)
+
+Remove the current element from the output. If the node is in an Array it will
+be spliced off. Otherwise it will be deleted from its parent.
+
+## this.delete(stopHere=false)
+
+Delete the current element from its parent in the output. Calls `delete` even on
+Arrays.
+
+## this.before(fn)
+
+Call this function before any of the children are traversed.
+
+You can assign into `this.keys` here to traverse in a custom order.
+
+## this.after(fn)
+
+Call this function after any of the children are traversed.
+
+## this.pre(fn)
+
+Call this function before each of the children are traversed.
+
+## this.post(fn)
+
+Call this function after each of the children are traversed.

+
+[![Build Status](https://travis-ci.org/przemyslawpluta/node-youtube-dl.svg?branch=master)](https://travis-ci.org/przemyslawpluta/node-youtube-dl) [![npm version](https://badge.fury.io/js/youtube-dl.svg)](https://badge.fury.io/js/youtube-dl)
+
+Download videos from youtube in node.js using [youtube-dl](http://rg3.github.com/youtube-dl/).
+
+If you're only interested in downloading only from youtube, you should consider using [pure Javascript youtube downloading module](https://github.com/fent/node-ytdl).
+
+## Installation
+
+With [npm](https://www.npmjs.com/) do:
+
+``` sh
+npm install @microlink/youtube-dl
+```
+
+## Usage
+
+### Downloading videos
+
+``` js
+var fs = require('fs');
+var youtubedl = require('youtube-dl');
+var video = youtubedl('http://www.youtube.com/watch?v=90AiXO1pAiA',
+  // Optional arguments passed to youtube-dl.
+  ['--format=18'],
+  // Additional options can be given for calling `child_process.execFile()`.
+  { cwd: __dirname });
+
+// Will be called when the download starts.
+video.on('info', function(info) {
+  console.log('Download started');
+  console.log('filename: ' + info._filename);
+  console.log('size: ' + info.size);
+});
+
+video.pipe(fs.createWriteStream('myvideo.mp4'));
+```
+
+It will produce an output that looks like the following when ran.
+
+```bash
+Got video info
+saving to T-ara - Number Nine - MV - 티아라-Seku9G1kT0c.mp4
+100.00%
+```
+
+### Resuming partially downloaded videos
+
+``` js
+var youtubedl = require('./');
+var fs = require('fs');
+var output = 'myvideo.mp4';
+
+var downloaded = 0;
+if (fs.existsSync(output)) {
+  downloaded = fs.statSync(output).size;
+}
+
+var video = youtubedl('https://www.youtube.com/watch?v=179MiZSibco',
+
+  // Optional arguments passed to youtube-dl.
+  ['--format=18'],
+
+  // start will be sent as a range header
+  { start: downloaded, cwd: __dirname });
+
+// Will be called when the download starts.
+video.on('info', function(info) {
+  console.log('Download started');
+  console.log('filename: ' + info._filename);
+
+  // info.size will be the amount to download, add
+  var total = info.size + downloaded;
+  console.log('size: ' + total);
+
+  if (downloaded > 0) {
+    // size will be the amount already downloaded
+    console.log('resuming from: ' + downloaded);
+
+    // display the remaining bytes to download
+    console.log('remaining bytes: ' + info.size);
+  }
+});
+
+video.pipe(fs.createWriteStream('myvideo.mp4', { flags: 'a' }));
+
+// Will be called if download was already completed and there is nothing more to download.
+video.on('complete', function complete(info) {
+  'use strict';
+  console.log('filename: ' + info._filename + ' already downloaded.');
+});
+
+video.on('end', function() {
+  console.log('finished downloading!');
+});
+```
+
+It will produce an output that looks like the following when ran.
+
+**Output:**
+
+``` sh
+[~/nodejs/node-youtube-dl/example]$ node resume.js
+Download started
+filename: 1 1 1-179MiZSibco.mp4
+size: 5109213
+^C
+```
+
+``` sh
+[~/nodejs/node-youtube-dl/example]$ node resume.js
+Download started
+filename: 1 1 1-179MiZSibco.mp4
+size: 5109213
+resuming from: 917504
+remaining bytes: 4191709
+finished downloading
+```
+
+### Getting video information
+
+``` js
+var youtubedl = require('youtube-dl');
+var url = 'http://www.youtube.com/watch?v=WKsjaOqDXgg';
+// Optional arguments passed to youtube-dl.
+var options = ['--username=user', '--password=hunter2'];
+youtubedl.getInfo(url, options, function(err, info) {
+  if (err) throw err;
+
+  console.log('id:', info.id);
+  console.log('title:', info.title);
+  console.log('url:', info.url);
+  console.log('thumbnail:', info.thumbnail);
+  console.log('description:', info.description);
+  console.log('filename:', info._filename);
+  console.log('format id:', info.format_id);
+});
+```
+
+Running that will produce something like
+
+``` sh

+
+You can use an array of urls to produce an array of response objects with matching array index (e.g. the 1st response object will match the first url etc...)
+
+``` js
+var youtubedl = require('youtube-dl');
+var url1 = 'http://www.youtube.com/watch?v=WKsjaOqDXgg';
+var url2 = 'https://vimeo.com/6586873';
+youtubedl.getInfo([url1, url2], function(err, info) {
+  if (err) throw err;
+
+  console.log('title for the url1:', info[0].title);
+  console.log('title for the url2:', info[1].title);
+});
+```
+
+### Downloading subtitles
+
+``` js
+var youtubedl = require('youtube-dl');
+var url = 'https://youtu.be/PizwcirYuGY';
+
+var options = {
+  // Write automatic subtitle file (youtube only)
+  auto: false,
+  // Downloads all the available subtitles.
+  all: false,
+  // Languages of subtitles to download, separated by commas.
+  lang: 'en',
+  // The directory to save the downloaded files in.
+  cwd: __dirname,
+};
+youtubedl.getSubs(url, options, function(err, files) {
+  if (err) throw err;
+
+  console.log('subtitle files downloaded:', files);
+});
+```
+
+### Downloading thumbnails
+
+``` js
+var youtubedl = require('youtube-dl');
+var url = 'https://youtu.be/PizwcirYuGY';
+
+var options = {
+  // Downloads available thumbnail.
+  all: false,
+  // The directory to save the downloaded files in.
+  cwd: __dirname,
+};
+youtubedl.getThumbs(url, options, function(err, files) {
+  if (err) throw err;
+  console.log('thumbnail file downloaded:', files);
+});
+```
+
+For more usage info on youtube-dl and the arguments you can pass to it, do `youtube-dl -h` or go to the [youtube-dl documentation][].
+
+### Downloading playlists
+
+``` js
+
+var path = require('path');
+var fs   = require('fs');
+var ytdl = require('youtube-dl');
+
+function playlist(url) {
+
+  'use strict';
+  var video = ytdl(url);
+
+  video.on('error', function error(err) {
+    console.log('error 2:', err);
+  });
+
+  var size = 0;
+  video.on('info', function(info) {
+    size = info.size;
+    var output = path.join(__dirname + '/', size + '.mp4');
+    video.pipe(fs.createWriteStream(output));
+  });
+
+  var pos = 0;
+  video.on('data', function data(chunk) {
+    pos += chunk.length;
+    // `size` should not be 0 here.
+    if (size) {
+      var percent = (pos / size * 100).toFixed(2);
+      process.stdout.cursorTo(0);
+      process.stdout.clearLine(1);
+      process.stdout.write(percent + '%');
+    }
+  });
+
+  video.on('next', playlist);
+
+}
+
+playlist('https://www.youtube.com/playlist?list=PLEFA9E9D96CB7F807');
+
+```
+
+### Getting the list of extractors
+
+``` js
+var youtubedl = require('youtube-dl');
+youtubedl.getExtractors(true, function(err, list) {
+  console.log('Found ' + list.length + ' extractors');
+  for (var i = 0; i < list.length; i++) {
+    console.log(list[i]);
+  }
+});
+```
+
+Will print something like
+
+``` sh
+Found 521 extractors
+1up.com
+220.ro
+24video
+3sat
+```
+
+### Call the `youtube-dl` binary directly
+
+This module doesn't have `youtube-dl` download the video. Instead, it uses the `url` key from the `--dump-json` CLI option to create a node stream. That way, it can be used like any other node stream.
+
+If that, or none of the above support your use case, you can use `ytdl.exec()` to call `youtube-dl` however you like.
+
+``` js
+ytdl.exec(url, ['-x', '--audio-format', 'mp3'], {}, function(err, output) {
+  if (err) throw err;
+  console.log(output.join('\n'));
+});
+```
+
+### Update
+
+Since the youtube-dl binary is updated regularly, you can run `npm run update` to check for and download any updates for it. You can also require `../lib/downloader` in your app if you'd like to place `youtube-dl` binary in a specific directory and control when it gets updates.
+
+``` js
+var downloader = require('../lib/downloader');
+
+downloader('path/to-binary', function error(err, done) {
+  'use strict';
+  if (err) { return console.log(err.stack); }
+  console.log(done);
+});
+```
+
+### Tests
+
+Tests are written with [vows](http://vowsjs.org/)
+
+``` sh
+npm test
+```
