This means that only the first call of any method will actually reach your object. All consecutive calls will be intercepted by the `Tacky` decorator, which will return previously calculated values. The decorator keeps all values in its internal `Hash`. If you want all methods of everything your methods return be cached too, you need to use "deep" caching (it's `true` by default): ```ruby obj = Tacky.new(obj, deep: true) ``` Keep in mind that `Tacky` is thread-safe. ## How to contribute Read [these guidelines](https://www.yegor256.com/2014/04/15/github-guidelines.html).
