This will create symlinks for all config files in your home directory. You can safely run this file multiple times to update.
One time:
git remote add upstream git@github.com:adarshpandit/dotfiles.git
git fetch upstream
git checkout -b upstream upstream/master
Each time you want to update:
git checkout upstream
git pull
git checkout master
git rebase upstream
