title: How to use the same issue labels in another repository?
body: <p>I want to apply my new issue labels to all of my repositories in Github.<br />
  I can make a new issue label (e.g. <code>important</code>) in a repository. (Let's call this repository <code>hello-repo</code>)<br />
  But I don't know how to use <code>important</code> in <code>bye-repo</code>.<br />
  Do I need to add a new label each time I create new repositories?</p>
