@yegor256, saw your next comment. From description of issue 356:

Puzzle 231-cb36cf7a in src/main/java/com/jcabi/github/DeployKey.java:41-41 has to be resolved: Deploy key object should be able to edit a deploy key. Let's create a test for for this method, declare it here, implement it in RtDeployKey and MkDeployKey, and add an integration test for it. See http://developer.github.com/v3/repos/keys/#edit. When done, remove this puzzle.

What comments should I remove in this case? Or it was removed before me. Is it?
