This is a wrong place to place a puzzle. You should place it where you see an impediment, a problem. In this case, the problem may appear in `MkGistTest`, when you create a method that tests `MkGist.remove()`. Your test should fail, then you should skip it with `@org.junit.Ignore` and there you add a `@todo` puzzle. Besides, pay attention to its formatting, see http://www.tpc2.com/dev/pdd
