 Wraps a value in an array if it isn't already one. Returns an empty array for `null` and `undefined`.
 
+A typical usecase for this: when you have an option that accepts multiple values as an array, but you want to make the use of an array literal optional when there's only a single value to specify.

+Some examples:
+
+```javascript
+var assureArray = require("assure-array");
+
+assureArray("hello world");      // ["hello world!"]
+assureArray(["hello", "world"]); // ["hello", "world"]
+assureArray(null);               // []

 ## API
 
-TODO
+### assureArray(value)
+
+Ensures that the provided `value` is returned as an array.
+
+* If `value` is an array already, this returns the array unchanged.
+* If `value` is `null` or `undefined`, this returns an empty array.
+* If `value` is any other kind of value, this returns a new array containing just that one value.
