1. Create a git remote for where you'll push the code on your server. 
git remote add production "root@188.226.210.218:/home/webapps/www/git-deploy"

2. This will initialize the remote git repository in the deploy directory
git deploy setup -r "production"

3.This generates default deploy callback scripts
