+> Returns an array with only the unique values from the first array, by excluding all values from additional arrays using strict equality for comparisons.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm install --save arr-diff
+```
+
+Install with [yarn](https://yarnpkg.com):
+
+```sh

+```
+
+Install with [bower](https://bower.io/)
+
+```sh

+```
+
+## Usage
+
+Returns the difference between the first array and additional arrays.
+
+```js
+var diff = require('arr-diff');
+
+var a = ['a', 'b', 'c', 'd'];
+var b = ['b', 'c'];
+
+console.log(diff(a, b))

+
+> Combines a list of arrays, returning a single array with unique values, using strict equality for comparisons.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/):
+
+```sh
+$ npm i arr-union --save
+```
+
+## Benchmarks
+
+This library is **10-20 times faster** and more performant than [array-union](https://github.com/sindresorhus/array-union).
+
+See the [benchmarks](./benchmark).
+
+```sh
+#1: five-arrays
+  array-union x 511,121 ops/sec ±0.80% (96 runs sampled)
+  arr-union x 5,716,039 ops/sec ±0.86% (93 runs sampled)
+
+#2: ten-arrays
+  array-union x 245,196 ops/sec ±0.69% (94 runs sampled)
+  arr-union x 1,850,786 ops/sec ±0.84% (97 runs sampled)
+
+#3: two-arrays
+  array-union x 563,869 ops/sec ±0.97% (94 runs sampled)
+  arr-union x 9,602,852 ops/sec ±0.87% (92 runs sampled)
+```
+
+## Usage
+
+```js
+var union = require('arr-union');
+
+union(['a'], ['b', 'c'], ['d', 'e', 'f']);
+//=> ['a', 'b', 'c', 'd', 'e', 'f']
+```
+
+Returns only unique elements:
+
+```js
+union(['a', 'a'], ['b', 'c']);
+//=> ['a', 'b', 'c']
+```

+
+Error handling for Vinyl plugins.
+
+## Usage
+
+```js
+var PluginError = require('plugin-error');
+
+var err = new PluginError('test', {
+  message: 'something broke'
+});
+
+var err = new PluginError({
+  plugin: 'test',
+  message: 'something broke'
+});
+
+var err = new PluginError('test', 'something broke');
+
+var err = new PluginError('test', 'something broke', { showStack: true });
+
+var existingError = new Error('OMG');
+var err = new PluginError('test', existingError, { showStack: true });
+```
+
+## API
+
+### `new PluginError(pluginName, message[, options])`
+
+Error constructor that takes:
+* `pluginName` - a `String` that should be the module name of your plugin
+* `message` - a `String` message or an existing `Error` object
+* `options` - an `Object` of your options
+
+**Behavior:**
+
+* By default the stack will not be shown. Set `options.showStack` to true if you think the stack is important for your error.
+* If you pass an error object as the message the stack will be pulled from that, otherwise one will be created.
+* If you pass in a custom stack string you need to include the message along with that.
+* Error properties will be included in `err.toString()`, but may be omitted by including `{ showProperties: false }` in the options.

+**A tiny wrapper around Node.js streams.Transform (Streams2/3) to avoid explicit subclassing noise**
+
+Inspired by [Dominic Tarr](https://github.com/dominictarr)'s [through](https://github.com/dominictarr/through) in that it's so much easier to make a stream out of a function than it is to set up the prototype chain properly: `through(function (chunk) { ... })`.
+
+```js
+fs.createReadStream('ex.txt')
+  .pipe(through2(function (chunk, enc, callback) {
+    for (let i = 0; i < chunk.length; i++)
+      if (chunk[i] == 97)
+        chunk[i] = 122 // swap 'a' for 'z'
+
+    this.push(chunk)
+
+    callback()
+   }))
+  .pipe(fs.createWriteStream('out.txt'))
+  .on('finish', () => doSomethingSpecial())
+```
+
+Or object streams:
+
+```js
+const all = []
+
+fs.createReadStream('data.csv')
+  .pipe(csv2())
+  .pipe(through2.obj(function (chunk, enc, callback) {
+    const data = {
+        name    : chunk[0]
+      , address : chunk[3]
+      , phone   : chunk[10]
+    }
+    this.push(data)
+
+    callback()
+  }))
+  .on('data', (data) => {
+    all.push(data)
+  })
+  .on('end', () => {
+    doSomethingSpecial(all)
+  })
+```
+
+Note that `through2.obj(fn)` is a convenience wrapper around `through2({ objectMode: true }, fn)`.
+
+## Do you need this?
+
+Since Node.js introduced [Simplified Stream Construction](https://nodejs.org/api/stream.html#stream_simplified_construction), many uses of **through2** have become redundant. Consider whether you really need to use **through2** or just want to use the `'readable-stream'` package, or the core `'stream'` package (which is derived from `'readable-stream'`):
+
+```js
+const { Transform } = require('readable-stream')
+
+const transformer = new Transform({
+  transform(chunk, enc, callback) {
+    // ...
+  }
+})
+```
+
+## API
+
+<b><code>through2([ options, ] [ transformFunction ] [, flushFunction ])</code></b>
+
+Consult the **[stream.Transform](https://nodejs.org/docs/latest/api/stream.html#stream_class_stream_transform)** documentation for the exact rules of the `transformFunction` (i.e. `this._transform`) and the optional `flushFunction` (i.e. `this._flush`).
+
+### options
+
+The options argument is optional and is passed straight through to `stream.Transform`. So you can use `objectMode:true` if you are processing non-binary streams (or just use `through2.obj()`).
+
+The `options` argument is first, unlike standard convention, because if I'm passing in an anonymous function then I'd prefer for the options argument to not get lost at the end of the call:
+
+```js
+fs.createReadStream('/tmp/important.dat')
+  .pipe(through2({ objectMode: true, allowHalfOpen: false },
+    (chunk, enc, cb) => {
+      cb(null, 'wut?') // note we can use the second argument on the callback
+                       // to provide data as an alternative to this.push('wut?')
+    }
+  ))
+  .pipe(fs.createWriteStream('/tmp/wut.txt'))
+```
+
+### transformFunction
+
+The `transformFunction` must have the following signature: `function (chunk, encoding, callback) {}`. A minimal implementation should call the `callback` function to indicate that the transformation is done, even if that transformation means discarding the chunk.
+
+To queue a new chunk, call `this.push(chunk)`&mdash;this can be called as many times as required before the `callback()` if you have multiple pieces to send on.
+
+Alternatively, you may use `callback(err, chunk)` as shorthand for emitting a single chunk or an error.
+
+If you **do not provide a `transformFunction`** then you will get a simple pass-through stream.
+
+### flushFunction
+
+The optional `flushFunction` is provided as the last argument (2nd or 3rd, depending on whether you've supplied options) is called just prior to the stream ending. Can be used to finish up any processing that may be in progress.
+
+```js
+fs.createReadStream('/tmp/important.dat')
+  .pipe(through2(
+    (chunk, enc, cb) => cb(null, chunk), // transform is a noop
+    function (cb) { // flush function
+      this.push('tacking on an extra buffer to the end');
+      cb();
+    }
+  ))
+  .pipe(fs.createWriteStream('/tmp/wut.txt'));
+```
+
+<b><code>through2.ctor([ options, ] transformFunction[, flushFunction ])</code></b>
+
+Instead of returning a `stream.Transform` instance, `through2.ctor()` returns a **constructor** for a custom Transform. This is useful when you want to use the same transform logic in multiple instances.
+
+```js
+const FToC = through2.ctor({objectMode: true}, function (record, encoding, callback) {
+  if (record.temp != null && record.unit == "F") {
+    record.temp = ( ( record.temp - 32 ) * 5 ) / 9
+    record.unit = "C"
+  }
+  this.push(record)
+  callback()
+})
+
+// Create instances of FToC like so:
+const converter = new FToC()
+// Or:
+const converter = FToC()
+// Or specify/override options when you instantiate, if you prefer:
+const converter = FToC({objectMode: true})
+```
