# well, you add an argument in your regex:

(r'^articles/(?P<year>\d{4}/(?P<month>\d{2})/?$, 'main.views.year_month'),

# That works fine, unless of course you want to show something
# different for just the year, in which case the following case can be
# used, making separate views based on the arguments as djangoproject

Go to Bitbucket and create a new repository (its better to have an empty repo)
    git clone git@bitbucket.org:abc/myforkedrepo.git
    cd myforkedrepo

Now add Github repo as a new remote in Bitbucket called "sync"
    git remote add sync git@github.com:def/originalrepo.git

Verify what are the remotes currently being setup for "myforkedrepo". This following command should show "fetch" and "push" for two remotes i.e. "origin" and "sync"
    git remote -v
