How to update files at remote website by running 'git publish'

git-publish.md

Alias for git is configured into the file .git/config:

[alias]
	publish = !sh ./scripts/publish.sh

The script file ./scripts/publish.sh looks like this:

#!/bin/sh
set -e
git push user@remote:path/to/clone/
ssh user@remote 'cd path/to/clone && git checkout -q -f'

Now it can be published by simply executing git publish.
