+====
+
+Missing shuffle function for arrays in javascript.
+This is [Fisher–Yates shuffle](https://en.wikipedia.org/wiki/Fisher%E2%80%93Yates_shuffle), and it's very fast.
+
+## Installation
+
+```
+npm install mess
+```
+
+## Usage
+
+```javascript
+var mess = require("mess");
+
+console.log(mess([1,2,3,4,5,6,7,8,9,0]));
+// output will be something like:
+// [ 7, 9, 2, 0, 6, 8, 5, 3, 1, 4 ]
+```
+
+## Why mess
+
+Because naming modules is hard and shuffle is already taken.
+
