+uniq
+====
+Removes all duplicates from an array in place.
+
+Usage
+=====
+First install using npm:
+
+ npm install uniq
+
+Then use it as follows:
+
+```javascript
+
+var arr = [1, 1, 2, 2, 3, 5]
+
+require("uniq")(arr)
+console.log(arr)
+
+//Prints:
+//
+// 1,2,3,5
+//
+```
+
+## `require("uniq")(array[, compare, sorted])`
+Removes all duplicates from a sorted array in place.
+
+* `array` is the array to remove items from
+* `compare` is an optional comparison function that returns 0 when two items are equal, and something non-zero when they are different. If unspecified, then the default equals will be used.
+* `sorted` if true, then assume array is already sorted
+
+**Returns:** A reference to `array`
+
+**Time Complexity:** `O(array.length * log(arra.length))` or `O(array.length)` if `sorted`
+
+
+## Why use this instead of underscore.uniq[ue]?
+A few reasons:
+
+* This library updates the array in place without making an extra copy (and so it is faster for large arrays)
+* It also accepts a custom comparison function so you can remove duplicates from arrays containing object
+* It is more modular in the sense that it doesn't come with a bazillion other utility grab bag functions.
