-Changing Issues to Pull Requests (Github)
------------------------------------------
-
-If you have have previously filed a GitHub issue and want to contribute code
-that addresses that issue, we prefer it if you use
-[hub](https://github.com/github/hub) to convert your existing issue to a pull
-request. To do that, first push the changes to a separate branch in your fork
-and then issue the following command:
-
-    hub pull-request -b davidhalter:dev -i <issue-number> -h <your-github-username>:<your-branch-name>
-
-It's no strict requirement though, if you don't have hub installed or prefer to
-use the web interface, then feel free to post a traditional pull request.
