-> Returns an array of unique values using strict equality for comparisons, maintaining the same order as the provided arrays .
+> Combines a list of arrays, returning a single array with unique values, using strict equality for comparisons.
 
+You can do this with just `[].concat.apply([], arguments)`, like [array-union](https://github.com/sindresorhus/array-union) but this implementation is much faster and more peformant. 
+
+For the most common use cases, this library is **20 times faster** than array-union. 
+
+```bash
+#1: five-arrays.js
+  array-union.js x 289,891 ops/sec ±0.70% (97 runs sampled)
+  current.js x 5,429,077 ops/sec ±0.81% (93 runs sampled)
+
+#2: ten-arrays.js
+  array-union.js x 161,132 ops/sec ±0.72% (98 runs sampled)
+  current.js x 1,725,939 ops/sec ±0.61% (97 runs sampled)
+
+#3: two-arrays.js
+  array-union.js x 376,238 ops/sec ±0.83% (95 runs sampled)
+  current.js x 6,817,593 ops/sec ±0.63% (94 runs sampled)
+```
+See the [benchmarks](./benchmark).

+## Other array utilities
+* [arr-diff](https://github.com/jonschlinkert/arr-diff): Returns an array with only the unique values from the first array, by excluding all values from additional arrays using strict equality for comparisons.
+* [arr-flatten](https://github.com/jonschlinkert/arr-flatten): Recursively flatten an array or arrays. This is the fastest implementation of array flatten.
+* [arr-filter](https://github.com/jonschlinkert/arr-filter): Faster alternative to javascript's native filter method.
+* [arr-map](https://github.com/jonschlinkert/arr-map): Faster, node.js focused alternative to JavaScript's native array map.
+* [arr-pluck](https://github.com/jonschlinkert/arr-pluck): Retrieves the value of a specified property from all elements in the collection.
+* [arr-reduce](https://github.com/jonschlinkert/arr-reduce): Fast array reduce that also loops over sparse elements.
+* [array-unique](https://github.com/jonschlinkert/array-unique): Return an array free of duplicate values. Fastest ES5 implementation.
