+Are you tired from casting objects and arrays to each other or are bored using is `isset`? Don't do those anymore! 
+Ary is a light class/function that makes accessing array items more convenient.   
 
 1. You can access array items using `->` or `['']` syntax.
 2. You will get `null` if an index does not exists (instead of a nasty notification!)
 3. You can specify a default value for missing indexes.
-
-* The class (`Ary()`) requires PHP 5.4 or newer.
-* The helper function (`ary()`) requires PHP 5.6 or newer. 
+4. You can set/get a value within a deeply nested array using "dot" notation.
