To push your changes to the live website, first set up a remote pointing to the server.
- With AFS:
git remote add live /afs/csail.mit.edu/group/cap/www.git
- With ssh:
git remote add live ssh://USER@sketch2.csail.mit.edu:/afs/csail.mit.edu/group/cap/www.git
Then, push to the server. Only the master branch needs to be pushed.
git push live +master:refs/heads/master
