Updating Slate

Add the remote, call it upstream:

git remote add upstream [email protected]:tripit/slate.git

Fetch all the branches of that remote into remote-tracking branches, such as upstream/master:

git fetch upstream

Make sure that you're on your master branch:

git checkout master

Merge our updates into your master branch:

git merge upstream/master

Push the updated code to Github:

git push

Publish the new changes to Github pages:

./deploy.sh
