I'm not sure I see the value in retaining the code of conduct in the README file with the addition of the CODE_OF_CONDUCT file. If it's best practice to have a separate code of conduct file, I think it should be removed from the README at the same time it is added to the code of conduct file.

@randomnote1 I agree. Raised the question in PowerShell/DscResources#337 just to be sure there is no legal issue by removing it. :)

Lets keep this open until we get answer on that issue.
