Wrong command in README (browse section)

just have a look at https://github.com/jingweno/gh#gh-browse

the last two commands mentioned start with `git` not `gh` is this correct, or just a typo?

    $ git browse -r resque
    > open https://github.com/YOUR_USER/resque
    
    $ git browse -r resque network
    > open https://github.com/YOUR_USER/resque/network
