Steps

1. Init local git repository (remember to create .gitginore with wp-config.php before staging anything)
2. Configure SSH-key access to server with git [https://help.github.com/articles/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent/, https://help.ubuntu.com/community/SSH/OpenSSH/Keys#Transfer_Client_Key_to_Host]
3. Init a bare repo on the server git init && git config core.bare true
4. Create a new post-receive hook with nano .git/hooks/post-receive (content see below!)
5. Execute chmod 755 post-receive on the script
6. Add remote to local repository git remote add staging user-name@your-domain.com:www/your-website
7. Try pushing git push staging master
8. Check if everything works as expected.
9. Add a .htaccess to the .git directory with content: deny from all
