If you are using the version of SD hosted on GitHub, you can now clone
and pull issues very easily. First,

#+BEGIN_SRC sh
    $ git config --global github.user franckcuny
    $ git config --global github.token myapitoken
#+END_SRC

This will set in your .gitconfig your github username and api token.
Now, when you clone or pull some issues using sd:

#+BEGIN_SRC sh
    $ git sd clone --from github:sukria/Dancer
#+END_SRC

sd will check your .gitconfig to find your credentials.
